Giving a vow experience to the end user (from look and feel perspective) is the aim of any front end developer. JavaScript is unarguably the most popular programming language. It offers rich OSS module ecosystem. Java’s vision of “write once, run everywhere” was eventually achieved by JavaScript. Like many other prevalent technologies, it has also evolved a lot over the years.

It was started in 1995 and is used by giant companies like Facebook, Walmart, Netflix and many more. Eliminating the shortcomings of the “so called” predecessor LiveScript, the JavaScript ecosystem became richer than ever. While creating the state-of-the-art User Interface, developers have a tough time choosing the right tool or technology. The list of available options literally goes endless. If you are a beginner, it’s hard to see the difference between HTML, CSS, and JavaScript – they may just seem like buzz words swirling around. However, to an experienced developer, it’s clear that the language that gives developers control and power to build complex frontend web applications is JavaScript.

Entire taxonomy of libraries and tools could easily be further sub-divided into lists of plugins, packages, add-ons, and other extensions. JavaScript is a world in itself. It’s not about a single language anymore, but about a range of flavors that all compile down to the same target. Primarily used to power the way websites look and function. It is used by 92.2% of web pages, and that dictates its popularity.

The rankings are based on thorough analysis of job postings on Dice.com and Indeed.com and Google search data. While Python topped the chart, JavaScript ranked third.

Another online research revealed some interesting findings. Library usage by country (defined as respondents who picked “have used before and would use again”).  

• Red indicates higher compared to worldwide average

• Blue indicates lower usage compared to worldwide average.

1. Despite ES6being a well-established standard by now, it will face some tough competition from trending heartthrob TypeScript. Undoubtedly it has started to dominate the typed JavaScript space.

1.Reacttotally dominated 2017. Further Vue’s followers are on the higher side as compared to Angular's diminishing popularity.

1. Although working on the client, developers still prefer Redux. However, the rise of GraphQLmight very well become the leader provided the huge wave of interest it is generating.

The talent gap is not getting bridged by the aspiring developers. Sadly, there is a huge margin between the job growth and the availability of qualified candidates. From a hiring perspective, it’s still hard to fill the roles.

The current trend in web development is to write in a higher level language that compiles to JavaScript. Even web apps that are built with ROR or Django will quite often use a good deal of JavaScript on the client side (in fact, it becomes a necessity if the app needs to be responsive). Flash became a thing of the past. JavaScript replaced it like a moonwalk. And it seems, for at least the next decade, it will continue to expand and take charge of an increasing number of digital responsibilities in varying parts of the stack. Does it have an expiration date? Sure, but we certainly don’t know it yet. But until the trend continues, demand for JavaScript developers will flourish.
