JavaScript is a fundamental language for building web applications. This programming language can handle a lot of tasks. Plugin development, complicated animations, and even back-end development are done with the help of JavaScript.

But before you begin to build your web application, you have to find an experienced developer. Easier said than done because the demand for web development is high, and companies try to attract qualified developers by any means.

That’s why this article is intended to shed some light on how to hire a JavaScript programmer.

JavaScript Developers Roles

JavaScript is a self-sufficient language that can single-handedly deal with every challenge on the way to web application development. Because of its extensive functionality, JavaScript developers are divided into roles according to their skills.

 Let’s take a closer look at the developer’s responsibilities.

1. Front-end JavaScript Developers

The responsibility of a front-end developer is to create a user-friendly interface for a web application. Their top favourite tools are HTML, CSS, and JavaScript. When developing the design of your web app, you should take several challenges into account.

One of them is a variety of screen resolutions. Front-end programmers should consider this nuance and develop adaptive UX design.

Another one, JavaScript is a high-level programming language that executes its processes on a client’s computer. Therefore, it’s optimization leaves something to be desired. That’s why developers should avoid irrelevant pieces of code and think beforehand.

2. Back-end JavaScript Developers

Further, you’ll have to find a person who will manage a server-side part of the project. Usually, back-end developers’ concern is a server, a database, and an application. So, the developer should be experienced in Node.js. This framework executes code outside of the client’s browser. Also, this position requires solid experience with databases such as SQL or MongoDB.

3. Full-Stack JavaScript Developers

Lastly, you need a jack-of-all-trades. That’s where full-stack developers appear. Whenever you need to build a quick prototype, they’re the best in it. Still, when developing some complicated design features or creating a database architecture, you shouldn’t rely entirely on full-stack developers. It’s better to pass specific requests to specialists in the required field.

JavaScript Developers and Their responsibilities

Different roles are engaged in different sets of activities. It’s time to learn what kind of tasks every specialist is responsible for.

1. Front-end JavaScript Developer

  • Developing UX-friendly design of an application.
  • Creating optimized solutions.
  • Perform unit-testing of different parts of code.
  • Documenting JavaScript, HTML, and CSS code
  • Cooperate with testers to eliminate bugs and exceptions.
  • Cooperate with the back-end developers while building the RESTful API.

2. Back-end JavaScript Developer

  • Optimizing server-side code to grant the fastest server-client response.
  • Integrating user-facing sections with the server.
  • Perform testing of Node.js based services.
  • Cooperating with the front-end team.
  • Keeping in touch with DevOps to monitor the server’s condition.

3. Full-Stack JavaScript Developer

  • Working with both front-end and back-end.
  • Designing architectures.
  • Creating initial prototypes.

JavaScript Developers and Stack of Technologies

Now, as we discussed roles and duties, let’s get to the requirements for the skills.

1. Front-end JavaScript Developer

Front-end engineers create the basic layout, semantic UI by using HTML5 and CSS3. To complement the formed base, developers should understand how to use Angular, React, Vue.js, or other frameworks. Also, to bring workflow to an order, engineers should know Web pack and Git.

2.  Back-end JavaScript Developer

JavaScript supplies engineers with a powerful tool for server-side development — Node.js. Alongside Express.js or Koa.js, it becomes incredibly efficient. To deal with databases, developers should have experience with SQL or MongoDB. As for API building, GraphQL or REST are good solutions, so your candidate should be acquainted at least with one of these technologies.

3. Full-Stack JavaScript Developer

As it was mentioned before, full-stack developers can deal with both front-end and back-end. But, they need to have proper experience with the majority of the technologies listed previously.

Things to Pay Attention While Interviewing JavaScript Developers

Apart from the tech stack, your future employee should have some basic skill set that every specialist should have. Let’s get through it.

  • Problem-solving skills It’s important not to panic with the first sign of problems, keep sane, and search for a solution.
  • Creativity If your candidate can come up with an alternative solution and see those details which no one else can see, he can become a valuable engineer in the future.
  • Teamwork Javascript developers depend on other departments while working on a project. They have to keep in touch with QA engineers, DevOps, etc. So, it’s significant to have established cooperation in your company.
  • Follow trendsDevelopers you hire should keep pace with fast-evolving technologies. That will give you advantages that brand new technologies bring into the sphere of web applications. So, make sure the candidate is acquainted with a couple of trendy programming languages and frameworks.

Now, let’s find out what to ask engineers during the interview.

How to Examine Hard Skills?

It’s impossible to imagine a JS developer who doesn’t know what prototype inheritance is. This definition may seem weird to you, but the average JS engineer should know the answer. To do a successful interview, you should have a list of questions. And most importantly, you should know what the answers are.

Here’s an example of questions for a JavaScript developer:

  • How to organize your code to ease the life of your colleagues?
  • What is the Observer pattern? Pros and cons of the Observer pattern.
  • What’s the difference between Relational DB and NoSQL?
  • What is function hoisting? Let’s talk about two ways of creating a function.

How to Examine Soft Skills?

Alongside hard skills, developers should have a pack of soft skills. They will improve their effectiveness in the workplace.

These questions will help you to understand your candidate better:

  • Tell about an important goal in your life and what efforts did it take you to reach it.
  • Were there some situations where you had to apply unusual programming methods during the projects? What was the outcome of this situation?
  • Were there any conflicts in your team? How did you get through them? How did you feel about the conflicts?

Places to Search for and Hire JavaScript Developers

Today, the IT market provides plenty of platforms to hire JS developers that will match all of your expectations.

You have several options on how to staff your team:

  • Hire freelance JS developers.
  • Create your team to work in the office.
  • Engage the services of an outsourced company.

Each course of events will lead to some advantages and disadvantages. So, it’s better to be informed about them beforehand.

1. Freelance JavaScript Engineers

Freelance is a trendy way to make a living today. A lot of developers prefer to be involved in the project remotely rather than spend their time in the office. They offer their services through special websites. I propose you to look at both sides of this two-headed coin.

Pros of Hiring JavaScript Engineers:

Freelance engineers are decent for developing small sections of the global project. Plus, they are usually the cheapest bid on the market. Thus, that may be a good idea to take the load off your main team bypassing a part of the work to freelancers.

Cons of Hiring JavaScript Engineers:

If you intend to hire freelancers as the development core of your project, prepare to assess their development skills yourself. You’ll have tough times to do that unless you’re an experienced developer yourself.

Furthermore, when planning on building a large project, take into account that it’ll not be enough to hire only one freelancer. A team of freelancers hired separately will face communication obstacles. The point is your team members may be located in different time zones, that’s why teamwork may be violated.

Moreover, it takes some time to get along with each other. Finally, developers can deliver the project with a lot of bugs or even disappear when they get their prepayment. In this case, all that remains is wasted time and a furious review on a freelance platform.

2. An In-house Team of Developers

Another option is hiring an internal development team. Thus, your employees will work in the office, and you’ll be able to monitor all the processes related to the project.

Pros of Hiring In-house JavaScript Developers:

If you’re not going to stop at a single project, then it’s better off thinking about long-term cooperation. You’ll be able to hire rookies, which in the future will master software engineering and stay loyal to your company (if you’ll treat them properly, of course). Furthermore, you won’t be abandoned by a half-functioning project. The in-house team will fix bugs and develop updates faster than whoever else.

Cons of Hiring In-house JavaScript Developers:

On the other hand, if you don’t have long-term prospects, an internal team may be very time and resource consuming. You have to manage the hiring process and make sure that every developer will find the right place in your company. ]]Also, experienced developers will expect you to pay a lot of money even if there were no tasks for them for some time. Lastly, you should keep in mind some side expenses like office rent, taxes, hardware and software purchases, etc.

3. Outsourced Team of JavaScript Developers

Today, a large number of companies prefer to use the services of outsourcing software development teams. This is where you can find a balance between the price, time frames, and quality. There are many offers available on the outsourcing market. Currently, Ukraine IT outsourcing, as well as Indian, has the biggest influence on the market. The reason is that vendors from these countries offer the most attractive price and a quality product.

So, how does outsourcing work? Someone has already built a team instead of you. All you have to do is to hire them, discuss the project requirements, and monitor how work is getting done.

Pros of Outsourced Team of JavaScript Developers:

The outsourced team of developers can build a project in the shortest period, among all of the listed options, and offers attractive prices. Also, the size of the team will be adjusted to the needs of your project, so you don’t have to pay for the extra workforce. Such companies always have a project manager who’s fluent in English.

Therefore, there won’t be any speech barrier when you want to inquire about the state of your order.

Cons of Outsourced Team of JavaScript Developers:

As well as with freelancers, you may find it hard to monitor the development process because of the time zones. Another one is client treatment. For now, outsourcing services in Asia are slightly cheaper than in Eastern Europe, for example.

But there were plenty of cases when Asian outsource IT companies didn’t meet their deadlines, that in result, cost a penny for their clients. Still, when chosen the right way, outsource IT companies are the most balanced option for quality solution delivery.

Wrapping up this section, we can see that the outsource development company is the best way for solution development in case of short-term cooperation. If you’re thinking about developing several projects, then it seems like the in-house team is your choice. What about freelancers, I can recommend them for the development of small parts of your project.

JavaScript Developer Rates

When it comes to rates, things become a little bit controversial. We have to divide developers by hiring options(in-house developer, freelancer, outsource team member) and take into consideration their country of residence. Let’s try to figure it out together.

How Much Do Freelancer JavaScript Developers Charge for Their Services?

Because of the unstandardized workflow, freelancers prefer to estimate the price for their services by counting working hours.

USA$81 to $100
Latin America$61 to $80
Asia & Pacific$61 to $80
Eastern Europe$61 to $80

As it’s seen, most high-priced developers are from the US. Others are more affordable. So, the daily price of a developer from Latin America or Asia, for an eight hour working day, is around $488-600.

How Much In-house JavaScript Developers Charge?

At this moment, things become slightly different. The main question is how much money you’re ready to pay to stay competitive as an employer.

From now, we will talk about the average salaries that internal engineers gain in the USA and UK. So, the average JavaScript programmer gains $112,000 per year in the US. Junior specialists can count on approximately $40,000 salary while experienced senior specialists can earn up to $215,000 per year.

In England, the average in-house team will be more affordable. An ordinary developer earns £45,000 per year. Junior specialists’ salary starts at £25,000, while senior JS engineers can get up to £70,000 a year.

How Much Do Outsourced Agency JavaScript Developers Charge?

Now, it’s time for the final category of developers. The overall situation is similar to freelance developers. The US has the highest rates, while Asia and Eastern Europe are the cheapest.

REGIONMIN. $/hMAX. $/hAVG. $/h
Latin America$30$50$40
Eastern Europe

Wrapping Up

I hope this article brought some understanding of the hiring process of JavaScript developers. No matter what hiring option you choose, always remember to ascertain your candidate’s knowledge and integrity. Also, try to avoid outsourced development companies with untrustworthy reviews.
