JavaScript is the “frontend” programming language. JavaScript is widely used to design interactive frontend applications. For instance, when you click on a button that opens up a popup, the logic is implemented via JavaScript.

These days, many organizations, particularly startups, are using NodeJS which is a JavaScript-based run-time environment. Node.js lets developers use JavaScript for server-side scripting — running scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser. Hence now with JS, you can use a single programming language for server-side and client-side scripts. If you are looking for that cool tech job at your favorite startup, you should seriously consider learning JavaScript.

Prons

  • Client-side JavaScript is very fast. It runs immediately within the web browser as there is no compilation requirement
  • Gives a richer interface to a website
  • Highly versatile
  • It is the programming language of the web
  • Reduced website server demand by virtue of being client-side
  • Regular updates via the ECMA specification
  • Several add-ons, such as Greasemonkey, for extending the functionality
  • Simplistic implementation
  • Plenty of resources and a mammoth community support
  • Used for building a diverse range of applications
  • Works exceptionally well with other programming languages

Cons:

  • Absence of copy or equivalent method
  • Allows only single inheritance
  • As the code executes on the user machine, many people choose to disable
  • JavaScript due to the fear of being exploited for a malicious intent
  • Might be interpreted differently by different browsers
