What JavaScript Development Companies Do and How Do You Find the Best One

When creating a software product, you will occasionally need the services of a JavaScript development company. For example, when you decide to outsource JavaScript developers.

How Do You Choose a JavaScript Development Company for Your Project?

With the constantly developing IT industry, building your own team of specialists is getting more and more difficult. This is especially true for large projects. That's why companies often choose to outsource professional JavaScript developers.

Let's find out more about expert JavaScript developer services and how you can choose the best contractor for your project.

What Is JavaScript?

JavaScript (JS) is a programming language, originally intended for frontend development. Today, JavaScript developers engage in frontend as well as backend. Everything a user can click on, fill out, and submit on a web page is created with JS.

JavaScript appeared in 1995, and, since then has actively evolved. Various libraries and frameworks constantly emerge to help JavaScript developers quickly and efficiently implement the necessary solutions. Today, JavaScript is known to be one of the most popular programming languages in the world, holding the leading position in most ratings.

Types of JavaScript Development Companies

Both small studios and the largest enterprises, involved in web development, choose JavaScript as their main programming language. Namely:

  • Web studios;
  • Web services and app developers;
  • Small specialized teams. Such JavaScript development companies usually provide outsourcing services.

 

If you order software product development on a turn-key basis, it makes no sense to study the availability and quality of JS elements separately. In this case, the overall result is more important. In fact, JavaScript development company services are more often required by dev teams themselves. This is true when, say, your team lacks JavaScript developers or simply doesn't have enough resources to implement your own projects.

Should You Hire a JavaScript Development Company or a Specialist?

Certainly, basic JS knowledge is a must for any web developer. Today, JavaScript developers work in a variety of organization types, including large enterprises and government corporations.

However, occasionally, situations happen when your in-house employees fail to cope with their tasks. Moreover, the best JavaScript developers are often engaged in a major project, while the company simply does not have enough human resources to implement other projects.

If a problem occurs on a regular basis, it probably makes sense to think about expanding the staff of your firm and hiring new JavaScript developers.

However, at the same time, you need to consider the following nuances:

  • The level of expertise varies widely, which makes quick finding a skilled developer for your staff a real challenge;
  • Educating your own staff is always a long process and requires the precise attention of your best JavaScript developers.

 

That's why expanding your staff is usually regarded as a strategic decision within the framework of business development.

If the project already needs to be implemented immediately, it's much more advantageous to seek help from third-party JavaScript developers.

JavaScript Development Company VS Freelancer. Who wins?

If you need one JS specialist for the duration of your project, perhaps, a freelancer will prove to be the most beneficial solution. The cost of the services of such a JavaScript developer will be lower than if you sign a contract with a web development studio.

However, in this case, make sure to do the following things:

  • Make sure that your chosen JavaScript freelancer has skills that correspond to the tasks at hand;
  • Prepare a clear and understandable technical requirements specification;
  • Be prepared to constantly monitor the work process of the JavaScript developer.

 

An experienced JavaScript development company will save you from the need for strict control since it has its own management and project manager. In addition, a professional web development agency usually has specialists of different levels in the staff.

Your project will be handled by a team of JavaScript experts, allowing you to optimize costs. If the project is simple enough, the contractor will engage a novice developer. If complex solutions and the latest JavaScript technologies are required, an experienced middle or senior-level developer will be involved.

How to Choose the Best JavaScript Development Company?

1. Check the cases and portfolios of the js developers. Pay particular attention to the quality of interactive element implementation. Also, make sure offered solutions fit your tastes and business needs.

2. Online reviews and customer feedback. It's important to understand that you're going to work with a reliable JavaScript development company that will get the job done in a timely manner.

3. Find out how many JavaScript developers will work on your project. Small web studios often have only one or two suitable professionals. This may not be enough for successful outsourcing. Thus, opt for well-adjusted teams.

4. Mind personal communication. It's important that the contractor's employees share the same values and fully understand your requirements.

Choose your partners wisely - the overall success of your software product depends on it.
