Javascript started humbly, it only used to powered the web adding interactivity to HTML pages which had once been boring and static. Mostly confused with Java another really hot language, some thought it was a scripting language for Java. It has since been the most popular programming language on the web.

Wait. Why did I say Javascript is a billion-dollar programming language. The answer is simple is used by the biggest of all companies, unicorns as well as the newest promising startups.

Javascript runs the web but that's is not the only place it exits, nowadays it's everywhere, from the web to native apps, to desktop, server side, to embedded devices. You can make really fast native apps with Javascript thanks to React Native. Node Js for server-side hence now we can run javascript on server-side something that was not there before. With these abilities javascript has very big companies like PayPal, GoDaddy went all-in with javascript when Node Js came out. I hope you know that Node Js is an implentation of javascript to run on server-side hence can be used in the back-end. They are not the only top companies that uses js though.

Here is how these billion dollars companies use Javascript

1. Facebook, uses js and even created React Js for their website front end and React Native for there for Facebook and Instagram apps. The good thing is that these frameworks are open source. Free to use so you can use them to make your next billion dollars apps.

2, Pay Pal we sort of talked about this above but PayPal is a giant online payment company. They deal with money and processing of payments is a really hard but they changed all their system to run javascript whereby they use NodeJs For back-end and vanilla Js on the front end.

3, GoDaddy, is also like PayPal they migrated to Javascript for backend and front end. As you may know that they are one of the largest domain hosting company and they process crazy ton of data all Using Nodejs on the backend js for the front end.

4, Walmart is the biggest retail store in the USA meaning they have intensive data to work on. They went all-in with Javascript too

5, Google, they are the king of search, they use a variety of technologies as well as programming languages but despite all that, they use javascript intensively on the front end, which power auto suggestion and display the search results. They have also implemented javascript to other programming languages such as the Dart that is used to make Flutter app for Android as well as iOS, They also created angular js that is used as front end framework.

So there you have it's the billion dollar programming language that powers the most powerful companies in the world. Hey, this is not the full list, there are other companies out there that use js in which if I decided to write all of them I would still be writing this post and not posted yet.
