JavaScript

Learn JavaScript step by step: variables, conditions, loops, functions, objects, the DOM and events, with solved exercise sessions.

About this course

This course takes you from your very first line of JavaScript to interactive web pages. Every concept is explained live in the editor, then put into practice with exercises and step-by-step solved exercise sessions (TD). What you'll learn: • The basics: variables, types, prompt and alert, type conversion, operators and comparisons • Control flow: conditions, loops, the ternary operator • Arrays: for...in, for...of, sorting arrays • Functions: regular, arrow and self-invoking functions, variable scope • Objects: literals, new Object, constructors, this, methods, getters and setters • The DOM: selecting, creating and modifying elements, working with forms • Events: onclick, addEventListener, mouse, keyboard, event propagation • Dates with the Date object The course ends with a full review , so you're ready on exam day. 33 videos · Solved exercise sessions · Review

Before you start

No programming experience needed. Knowing basic HTML and CSS helps for the DOM part (see the Web Development course). Get ready: • A computer with an up-to-date browser (Chrome, Edge or Firefox) • Visual Studio Code (free), ideally with the Live Server extension Tip: type the code yourself as you follow the videos, and open the browser console (F12) to see the results.
