The mother of all code - JavaScript is a backbone of most code that we create.
JavaScript is a software development programming language that is based on client-side scripting. It basically runs INSIDE the web browser that you currently use. Each modern browser comes with an interpreter that allows it to execute the incoming code on the go. Converters of all sorts, calculators and comparison engines are usually developed using JavaScript. Field validation can't live without it. The code is placed inside the basic structure of the website, separated from the HTML code by defined tag. Quite easy to learn, yet difficult to master - in proper hands, it's a foundation for software that can go beyond your imagination.
