But what about those to do ECMAScripting? Well a new open source webapp named JSFeatures.in answers that question nicely.
The site itself is bare yet highly usable. It places a focus on the content and it’s even mobile-responsive for smartphone users.
If you want to check out the source or submit a pull request you can visit the JS Features GitHub page.
Anyone should be able to clone the repository for themselves to update, append, or change any of the code guidelines. This makes JSFeatures.in a portable & highly customizable resource for developers.
