JavaScript Challenge

Test your knowledge of the fundamental concepts of JavaScript

In this challenge, you will face more than 40 JavaScript exercises. These exercises are divided into different categories as follows:

Functions:

Use a function, retrieve parameters, return a result, etc.

Types:

Check the type of a variable, detect an undefined variable, etc.

Conversions:

Convert a string to an array, then to an object, etc.

Manipulations:

Invert an array, cut a string, determine the smallest existing number, etc.

Dates:

Check the validity of a date, calculate the difference in days between two dates, determine if a given date is a leap year, etc.

Objects:

Loop through an object, change an object's property, clone, invert, etc. It is preferable to have a basic understanding of JavaScript to progress comfortably. However, the difficulty of the exercises gradually increases and it is entirely possible to tackle this JavaScript challenge without having an advanced level. The goal here is to work on algorithmic thinking and practice. Each exercise contains a statement explaining the steps to follow, as well as documentation on the concepts needed to solve the problem.

What you will learn

- Apply your JavaScript knowledge - Improve your logical thinking - Understand how an algorithm works - Make progress in the face of increasing difficulty
