Top 10 Startups Using JavaScript

Most of our interaction on the internet nowadays is dependent on the interactivity that comes with coding using JavaScript.

Almost 97% of the websites on the internet today use JavaScript with third-party libraries for client-side page activity. Turn off JavaScript, and you will see some websites partially or completely shut down, including the likes of Netflix, Google Maps, etc.

One of the primary reasons why JavaScript is universally popular is the fact that JavaScript is extremely easy to set up. With other programming languages, you need to download and create a development environment. On the other hand, every browser supports JavaScript, making it so popular in the start-up culture.

Registered users can post videos, photos, links, or texts in dedicated threads or “subreddits” for different topics. Other users can then upvote, downvote, and comment on the post to share their thoughts and perspectives.

Posts with more upvotes (or karma points) are further up on the start page and are usually an indication of a better quality of the post.


Slack makes it easier to connect to your teammates; you work in dedicated spaces called channels where you can collaborate with people inside and outside your organisation just as you would in person.
