JavaScript Online Training

JavaScript is usually the first programming language you will need to learn, and this Specialization will help you practise and build your skills through a gradual progression of modules and courses.

JavaScript Course Description

JavaScript is a scripting language that is interpreted, dynamically typed (weakly), and used mostly for web development. It can be used to connect to the DOM in the browser so that it can be controlled by code. It's a simple way to say that it can be used to change how web pages work. Most of the time, JavaScript is used to script on the client side.
