Advanced Introduction to JavaScript

Duration: 81.58 min.   Views: 27786

Some software developers have an impression that JavaScript is a second-league interpreted language with the main purpose of making Web pages a little prettier. The reality is different though. JavaScript is a powerful, flexible, dynamically typed language that supports object-oriented programming. JavaScript functions are the first class citizen that can live their own lives as opposed to Java’s methods.
