What is JavaScript

No matter what stage you are in your search for quality Javascript developers, it’s safe to say you’ve noticed there’s a lot of options for hiring talent. Javascript is considered to be the most popular programming language in the world in terms of its overall usage in development. It’s growth as a preferred language doesn’t seem to be slowing down, it’s safe to say JS will be around for the foreseeable future. With such a huge amount of “qualified” developers out there, it’s important you are going the extra mile to ensure who you hire is actually what you need for your project. Understanding the development landscape that Javascript fits into should give you more insight into how to plan your next project using it.

What is a JavaScript Developer?

A JavaScript developer is essentially a software developer that is proficient in using JavaScript and various technologies built using it. As a developer, there is a choice to be made as to whether to become a full-stack developer or focus either on the front-end or back-end. 

Full-stack JavaScript developers end up learning front-end frameworks, middleware, back-end technologies such as Node.js and database technologies MongoDB and PostgreSQL. 

Front-end developers focus only on user-facing technologies and frameworks such as Angular and Vue.js, but also can invest their time being specialists using the React library. 

Back-end developers focus on mastering how to wrestle with business logic and APIs to ensure that databases are used properly and that the web page is served to the end-user. 

Why JavaScript?

What makes Javascript so popular? Many developers would tell you the versatility of the language to create a wide range of applications and modules that scale and work seamlessly across a variety of platforms. Javascript is most commonly used to create dynamic web-apps, oftentimes powering the front-end, though it isn’t always limited to that. There are many instances of companies using parts or all of Javascript to run the back-end of their web services, a perfect example of the versatility of this programming language.  

Javascript sets itself apart from other languages by being fairly quick for a high-level language, and conveniently portable. It’s a very accessible way to create stable web-apps that work across desktop, mobile and different web browsers within these ecosystems. Programming using JavaScript technologies gives you the power to ensure your user’s experiences are quick and stable across all platforms that your web-app is accessed on.  

Some of the biggest companies in the world are using Javascript to power parts, or the entirety of their web-apps. To name a few: 

  • Google
  • Facebook
  • Netflix
  • Paypal
  • LinkedIn

Many of these companies have made the switch from Java to Javascript due to JS’s more well-suited ability to handle large amounts of data and server processing without diminishing performance. As the web-app landscape has developed to become more complicated, with more dynamic websites that are reflective of individual user experiences, a programming language that can handle more complicated processes becomes necessary. 

Why developers like JavaScript

  • Can be used on front-end/back-end
  • Fast
  • You can't get a device today that doesn't run js
  • Expressive
  • Executed on the client-side
  • Lightweight

JavaScript Alternatives & Comparisons


TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.


Dart is a cohesive, scalable platform for building apps that run on the web (where you can use Polymer) or on servers (such as with Google Cloud Platform). Dart language, libraries, and tools can be leveraged to write anything from simple scripts to full-featured apps.


CoffeeScript adds syntactic sugar inspired by Ruby, Python, and Haskell in an effort to enhance JavaScript's brevity and readability. Specific additional features include list comprehension and de-structuring assignment. 


Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere and the primary enterprise-level language in use today.

Hire A JavaScript Developer

JavaScript developers are fairly common these days as it is one of the most popular programming languages around right now. However, finding a good developer is not as easy as it seems. With all of the freelance marketplaces and job boards around, you’d think it would be easy to find your rockstar and get started. So why is it so hard? How do you go about deciding if a developer joins your team? 

For the second question, we have a great resource for you to check out that addresses that topic in much greater detail. 

As for the first question, the reason it’s so hard to find good developers is not that there aren’t any around, there are plenty. But there are also plenty more developers that are just average at best, and even more that aren’t worth the risk of hiring.

There are many reasons why this happens, and it seems that the Pareto principle (80/20 rule) is at work here, but the main reason is that JavaScript is fairly easy to pick up. Once a developer understands the basic concepts of JavaScript and a library or framework, they can start building some simple applications right away and that’s great. However, as applications increase in complexity, so does the knowledge required to build that complexity increase.

Developers grow in so many different ways, the only way to make sure that they are able to code their way out of a paper bag is to test them and see what they’re made of. It’s an important part of the hiring process that is easily botched by inexperienced hiring managers and business owners alike.

The Importance of Web Applications

It used to seem like mobile apps were set to take over the way we do everything, and in a lot of ways, it has had a large impact on how we access the company’s services through the internet. Despite mobile relevance, web-apps have established themselves as one of the most powerful ways to deliver digital solutions to customers. With the growing capabilities of websites through new developments in technology and optimized usage of languages like Javascript, it’s becoming possible to services and functionalities that used to exclusively be found through Windows or Mac desktop applications that had to be installed on your machine. With these new capabilities, it’s a lot easier to keep your web-app updated, ensuring your customer’s experiences are the same across platforms. The ability to do this, and scale the experience across multiple platforms without sacrificing performance is what makes web apps extremely important for building, and managing a cloud-based SaaS business. Javascript has had a huge part in paving the way for a web-app ecosystem that powers the future of business online.
