Front-end developers are responsible for a websiteâs user-facing code and the architecture of its immersive user experiences. In order to execute those objectives, front-end devs must be adept at three main languages: HTML, CSS, and Javascript programming.
On the back-end, you can use many languages, including Java, PHP, C#, and (only since a few years) JavaScript with NodeJS. The main adavantages of using JavaScript with NodeJS on the back-end are: Since you anyway need to be good at JavaScript programming for doing your job on the front-end, if you are also using it on the back-end, you only have to master a single language (and its tooling), instead of two. That's a huge benefit.
