It really depends on what is it you want to accomplish with your code, JavaScript is a good language to learn because it can be used to build a lot different things, I’ve even seen tutorials on creating a blockchain with JS, also freecodecamp.org does an amazing job of walking you through the language and the online community is very active. Of course, if there is something specific you want to accomplish there are languages that are more suited for those jobs. JavaScript will always be your best friend for building the front end of websites.
