What is JavaScript?

JavaScript is a cross-platform, object-based scripting language. It supports a runtime system based on a small number of data types representing numeric, Boolean, and string values. It has a prototype-based object model which provides dynamic inheritance. It also supports functions without any special declarative requirements. It is a very free-form language because variables, parameters and function return types are not explicitly typed.

Ok enough of that. JavaScript has been reborn as a declarative language. It runs on the front end, the back end, and the database. One can master JavaScript and become a true full stack developer. It's free to use and you can easily write it on something simple as notepad or something as complex as an IDE.

YOU can become a JavaScript developer but YOU must put in the time to do it. I was on an interview once as was told "Oh you're not a PHP developer? You just do JavaScript? You are not into heavy lifting". I thought to myself "I do not need your heavy PHP language. I can do EVERYTHING with JavaScript!".
