GFE 75 Challenge

A collection of JavaScript challenges from GreatFrontEnd that help you master fundamental programming concepts and improve your problem-solving skills.

In this series:

1

How to write your own debounce function

2

Building your own reduce array method

Learning how the internals of JavaScript works is a great way to master the language you use every day. Let's challenge our knowledge!
3

Replicate the classNames function

The classNames function is one of my favourite helpers when I create components. It plays so nicely with Tailwind and thanks to this GFE 75 challenge.
4

Flatten an array with a custom function

Let's learn how to implement our own flat function to discover how the designer of the JavaScript language thinks and learn from their intuitions.
5

Building the throttle function

Like debounce, the throttle function is really useful to optimize our function calls. This time, instead of importing from Lodash or any other alternative, we learn how to build our own.
6

Building a todo list in React

A todo list is maybe the first app you ever build, in this article I describe how I solved this challenge inside the GreatFrontEnd platform.
7

Build a contact form withouth JavaScript

Nowadays we rely on JavaScript for almost everything, but do you know we can handle a form even without and keep a nice user experience?
