JavaScript is a dynamic, multi-functional, client-side programming language. Developers can write it directly in the HTML of a web page. Built by Mozilla’s co-founder Brendan Eich, JavaScript brings amazing interactivity to web pages. It’s fascinating how the logic behind it allows creating responsive layouts that enrich user experience.

As the second most popular programming language, JavaScript powers today’s Internet ecosystem. It’s diverse, straightforward and efficient. Scripts, which are the building blocks of this language, are written in plain text. Thanks to the JavaScript engine, commands can execute in any browser, server or device which has the engine installed.

JavaScript is both lightweight and flexible. Developers can enhance the JavaScript core with various features to make the resource even more engaging. Such features could be anything from third-party libraries and frameworks to browser APIs.

At the same time, JavaScript allows both functional and object-oriented coding. This makes it easy for programmers to build any function or object by means of JavaScript only.

More specifically, JavaScript can perform a whole variety of tasks. For example, it can:

  • show messages to website visitors;
  • store the data locally, i.e. on the client side;
  • display dynamic content on a web page, for example interactive maps, videos, graphics, etc.;
  • redirect file download and upload requests to remote servers, and much more.

JavaScript’s robust functionality does not end here. What really sets it apart is a combination of three qualities:

  • it is the only programming language compatible with all most popular browsers;
  • it integrates fully with HTML/CSS;
  • it puts simplicity front and center.

If that were not enough, the JavaScript ecosystem is so diverse that there is now a whole number of languages and transpilers that run on top of it. These range from TypeScript and Dart to Elm and Reason. Such diversity empowers developers to make complex applications mature and efficient as well as bypass limitations of JavaScript.


Applicability of JavaScript is quite impressive. Some of the most common examples of its implementation include:

  • user interfaces;
  • web development and web applications;
  • server applications;
  • game development;
  • social media;
  • mobile apps;
  • smartwatches, etc.

Some interesting facts about JavaScript reveal even more about this language’s genuine potential. For example:

The future looks very bright for this scripting language, which means the world will see even more JavaScript-powered solutions in the coming years.


  • Super fast on the client side. Since JavaScript runs inside the client-side browser, its implementation can load very fast, provided it’s done properly.
  • Less intense server load. With JavaScript living on the client side, website servers no longer have to handle that extra load. The website runs faster and users get a smoother experience.
  • Sophisticated environment. Environments like Node.js help dev teams overcome JavaScript’s limitations, e.g. execute network requests or handle arbitrary files.
  • A wealth of frameworks and libraries. React.js, Angular.js and Ember.js are just a few examples of the most popular JavaScript frameworks. Coders can use them to bring an edge to their solutions.
  • Prototypal inheritance. In JavaScript, objects inherit from other objects. Programmers no longer have to handle classes, which makes coding simpler and faster.
  • Multi-functional interfaces. Drag and drop functionality speeds up developers’ work. This results in beautiful and compelling websites and applications that work well across all browsers and devices.
  • Interoperability. Coders can use JavaScript in partnership with other languages. It does not depend on any file extension and can even be written directly in PHP- or Perl-based scripts.
  • Short learning curve. With JavaScript, the dev teams can get up and running quite quickly. Because JavaScript is everywhere, programmers will find tons of dedicated tutorials and documentation online.


  • Security on the client side. Working on the client side may be a powerful feature when it comes to speed, but it’s quite lax in terms of security. Because the program executes on a user’s device, the code can be subject to malicious use.
  • Browser support. Dev teams must perform extensive testing to ensure that the program executes properly across all browsers. Unlike server-side scripts, client-side scripts might not always produce the expected output.


An ideal JavaScript developer you’d want to hire should be proficient with a whole number of development techniques and tools from the programmer’s kit. The skill set and experience will not only determine the salary structure, but also the success of your project in the long run.

Apart from the HTML knowledge which must come by default, here are the top skills to expect from a dedicated JavaScript coder.

  • Asynchronous coding. A skilled JavaScript coder can set the program to complete multiple commands at any one time, rather than wait for each command to execute before moving along to another one. This skill is crucial to unlocking the true speed potential of JavaScript.
  • Functional coding. You definitely want your programmers to create concise, clean and efficient code. Coders that mastered functional coding can do just that. This is not to mention that functional coding eliminates data mutation, shared states and unpredictable outcomes.
  • Memory management. A skilled developer can optimize memory use and ensure that it doesn’t consume most resources. This accelerates performance and minimizes the risk of memory leaks.
  • Cross-browser coding. JavaScript outperforms all other programming languages in terms of browser compatibility but this comes at a price. Developers must handle extensive testing to ensure the program’s smooth execution across browsers.
  • Proficiency with jQuery. JavaScript is powerful on its own but couple it with libraries like jQuery, and you’ll end up saving tons of time. Optimization is important and developers must know the shortcuts where they’re due.
  • CSS. In a nutshell, JavaScript developer must have an in-depth knowledge of CSS. From reprocessing to frameworks, it’s crucial for a frontend developer to master this language.
  • Version control. There’s always a looming possibility that the latest change in code can wreck the entire program. With it, months of carefully planned work will be gone. A dedicated developer doesn’t take unnecessary risks and learns version control instead with handy tools like Git.
  • Web performance tools. Users won’t hesitate to abandon even the most compelling website if it fails to load fast. There are plenty of development techniques to boost performance, but the essential part is for developers to use automation tools to put this process on a fast track.
  • Hands-on experience with testing/debugging. Bugs and errors are pretty much the part of the developer’s work. A dedicated JavaScript coder knows the ins and outs of the unit and functional testing. And not just that – the tools that automate testing, too.
  • Responsive design. SEO and user experience benefits of responsive websites and apps are huge. A skilled JavaScript programmer must know the mechanisms within scripts and frameworks that can make or break a responsive asset.

Last but not least is your developers’ ability to learn. The JavaScript ecosystem changes all the time. At the end of the day, it’s all about the right choices of tools and development techniques.

When it comes to your project, the skills and expertise of a development team in charge are instrumental to your success. There are many benefits of hiring JavaScript developers online versus locally.

  • Technology stack. You don’t want to hire any talent. You need a team that understands your business goals and can build technology that will get you there. It might be hard to find that talent locally. By resorting to online search, you get access to a whole new pool of exciting opportunities you might be lacking at home.
  • Project costs. Salary expectations come to the fore for any project so it’s essential to understand your costs right from the start. Just like with the skill set, finding local talent for an acceptable salary may become a challenge. A remote dev team is always much more cost-effective.
  • Bypass the need to employ an in-house team. Not every business can put up with the strain of hiring an in-house JavaScript team, but that doesn’t have to be a problem for you. You can level the playing field by hiring a dedicated remote team to take charge of your project. The usual complexities of in-house team management will be a thing of the past.

All in all, hiring a remote JavaScript team to power your project can be the best business decision for the project you’re passionate about.
