Learn the basics about functions in JavaScript:

  1. Basic theory about functions in JavaScript.
  2. Learn the syntax on how to create functions.
  3. How to call functions.
  4. What are function parameters and the return statement.
  5. How to create traditional, arrow and anonymous functions.
  6. Use functions in different scenarios, like for replacing vowels in a string.

These exercises are intended to be built by collaboration, we need you! If you find any bugs or misspells please contribute and report them.

How are the exercises organized?

Each exercise is a small React application containing the following files:

  1. app.js: represents the entry file for the exercise.
  2. README.md: contains exercise instructions.
  3. test.js: you don't have to open this file, it contains the testing script for the exercise.

Note: The exercises have automatic grading, but it's very rigid and strict, my recommendation is to not take the tests too serious and use them only as a suggestion, or you may get frustrated.
