Hire a JavaScript Developer


Do you have a web project that requires a developer or a whole JavaScript development team? We will provide you with such resources! Polygant has a unique pool of specialists with the necessary programming skills and considerable experience in JavaScript development. They are proficient in both JavaScript and frameworks with libraries.

The JavaScript developers we recommend can work in a team, understand technical specifications and documentation, can deal with someone else’s code and fix bugs. They are ready to participate in all stages of your project to ensure functionality and optimisation. If necessary, they will continue to support the product after release.

Hiring a ready-made development team is a good way to save on staffing services and reduce the time from the beginning of development to the implementation of the project and changing its status to the open-access project.

JavaScript and JavaScript Developers

According to the TIOBE index, which estimates the popularity of 100 programming languages, JavaScript ranks seventh again in 2021. The rating is updated monthly, but the position of this language is firm: it has been in the top ten since 2001. It turns out that JavaScript has been with us for a long time and will be with us for a long haul.

The first thing to know is that JavaScript (JS) and Java are not the same things. Yes, the names are similar, as are the internals: JS is based on Java and C. There is one more language with a similar name. It is called JScript. All three languages are similar but not the same since they serve different purposes and require different knowledge. A JavaScript developer will not apply for a Java job, and a Java developer will not replace a JavaScript developer.

JavaScript at a glance

JavaScript is a multi-paradigm language that supports object-oriented, imperative, and functional styles. It was created by Brendan Eich in 1995 to make web pages interactive. This programmer is known for Netscape Navigator, Mozilla Firefox, and Brave browsers.

A feature of JS is its low barriers to entry, so it is usually the first language in which future developers learn to program. This is how it was conceived: so simple that it could be understood even by non-programmers (for example, designers).

JS programs are called scripts. They connect to HTML in the browser and run when the web pages are loaded. This language allows you to do simple things in easy ways and fully integrate with HTML and CSS. To achieve cross-browser compatibility while developing web applications, JS frameworks with libraries are used.

What JavaScript developers do

They write the code, and then they test it. We mean automatic tests that are programmed additionally. Then they debug the program and fix the errors. They profile the code, i.e. optimise it to run faster and use fewer system resources.

A developer can only specialise in front end (client side) or back end (server side). The client side is what the user sees, and the server side is the internal business logic. And there are full-stack developers. They are universal specialists who work with databases, mark up layouts, and even do system administration.

Where JavaScript is applied

The language is simple, and there are many programmers. Does it mean that it is a low-paid primitive activity for solving small tasks? That’s clearly not the case. JS is used to write scripts for space flight missions, program microcontrollers for smart homes, train artificial intelligence, analyse the neural activity of the human brain, etc.

However, there are not so many space engineers and neurophysiologists as there are owners of client-server applications. JS is used on the client side for programming the user interface (appearance and behaviour of screens) and for sending commands to the server.

Although JS was originally targeted at browsers, it can also be executed outside of them. With the help of the interpreter, scripts can be run anywhere. It is also used for writing mobile applications, widgets for the desktop, macros for office programs, and scripts for Photoshop. There is even a Linux operating system emulator written in JS. It is a powerful language. Therefore, it is very popular.

What skills professional JavaScript programmers have

What to look for in a CV:

  • mastery of interface layout (HTML5, CSS, Bootstrap, responsive web);
  • knowledge of object-oriented programming;
  • use of design patterns (MVC, MVP, MVVM);
  • use of frameworks (AngularJS, jQuery, Node.js, React, Vue.js);
  • experience of using version control systems and repositories (Git, GitHub);
  • readiness to write unit tests;
  • familiarity with the continuous integration and continuous deployment (CI/CD) practices and tools;
  • skill in handling module bundlers (Babel, Webpack).

JavaScript programmers are involved in working out technical solutions. Close cooperation with a team requires soft skills: the ability to clearly and delicately argue one’s point of view, show initiative, make decisions, and bear personal responsibility.

Is the company multinational, are the stakeholders foreigners? Check the candidate’s ability to understand cultural differences. It is not enough to know technical English. They must follow the rules of business correspondence that are used abroad.

What to do if you need a JavaScript developer

When you know about universal full-stack developers, you may want to hire one of them. This would suit a small business. However, it makes more sense to hire specialised JavaScript developers for a large project: one or two for design, plus a few more for internal services. The only full-stack developer would be overwhelmed. Besides, it is difficult to replace such an employee: all work is tied to one person, all knowledge is in one head. And a jack of all trades loses to a narrow specialist in the depth of knowledge. This will affect the quality of the product.

Searching for a freelancer

The rates of programmers in the capital are 2-3 times higher than the regional ones. That is why even conservative companies are enthusiastic about hiring remote JavaScript programmers. For the money that a newbie from the capital will ask for, there is a strong professional in the provinces.

Freelancers, however, are more difficult to control. You never know exactly where they are, what they do, you can’t call them for an emergency meeting, and sometimes you don’t even know what they look like.

Hiring a staff member

The shortcomings of staff members are not only bureaucratic. They are paid for all hours, even those when a high-rated programmer flips through social networks, drinks coffee, or is idle while the customer is testing the application.

But a staff member is always in sight. They are deeper integrated into the team, aware of the specifics of the business, and participate more effectively in discussions. Video calling is convenient, but sometimes it’s important to sit at the same table.

Outsourcing a team of remote JavaScript developers

JavaScript is not a case where the difference between outsourcing, recruiting, and freelancing is tangible. If you are implementing a complex technology that requires a whole set of hardware, software, and rare skills, then it is better to resort to outsourcing since a well-coordinated team of experienced JavaScript developers will give a guaranteed result. The language itself does not require complex solutions, but sometimes it is part of them.

The benefits of outsourcing JavaScript developers are organisational rather than competency-related. For such employees, you do not have to pay taxes and submit reports. They do not need to be trained, motivated, and controlled. Outsourcing is also convenient for hiring: no need to delve into the details of the profession, conduct dozens of interviews, and check test tasks.

Hourly Rate: 50 USD (45 EUR)

JavaScript developer labour market

When you first explore the market, you might wonder: if everything is so simple, then where do these huge numbers in expected salaries come from? The point is that JS is potentially vulnerable to attackers. For example, hackers steal bank card information that a customer enters for payment on a website. Such vulnerabilities are preventable. And while writing code in JS is easy, plugging security holes is difficult. Also, you need to ensure that your program is cross-platform so it could work on all devices. Only experienced programmers can do this, hence the high salaries.

There are many JavaScript programmers on the labour market, and there are plenty to choose from. You can see prices for any budget: both a modest startup and a large business will find the right employee. The salary depends on work experience, specialisation, and technology stack.

JavaScript developer salaries in the UK

Jokes about British scientists do not apply to British programmers: the demand for them is constantly growing. Junior devs will ask for 30,000 pounds, middle devs will prefer 45,000 pounds, and senior devs require 70,000 pounds. Europeans define the annual salary in the contract, not the monthly one. And do not be surprised if a developer from the UK asks to transfer money once a week — that’s what they do.

Market average hourly rates: from 25 to 60 GBP depending on skill level and technology stack.

JS developer salaries in Russia

Russian programmers are valued all over the world for their ability to solve non-standard problems with selflessness and inexpensiveness. The monthly salary of a JS developer in a company ranges from 50,000 to 200,000 Russian rubles. The lower limit is for junior devs, and the upper limit is for senior devs.

Market average hourly rates: junior—700 RUB, middle—1300 RUB, senior—2000 RUB per hour. In euros, it is about 8 / 14 / 22 EUR, respectively.
