Any browser has it, which means you don't have to take pains setting up a special environment, downloading/installing code editors, compilers, etc.). It's probably one of the reasons that make JavaScript the most used programming language in the world (used by 85% of full-stack devs, for example). Another great advantage is that JavaScript is easy to learn if you learn properly. Also, there's an abundance of jobs for JavaScript specialists offering a high pay rate (around $95k in the US on average).
