Introduction to JavaScript Programming

About this course

JavaScript is one of the most widely used programming languages in the world. It powers websites, web applications, and interactive user experiences across industries.

This course is for people who have little or no programming experience. It introduces the core ideas of programming using JavaScript. Delegates will learn the basic building blocks of programs and how they work together. You will learn how to read and write small programs, understand how code works, and start solving real problems.

If you already know HTML and CSS, this course is the first step toward building smarter web solutions.
