Dozens of looping exercises to sharpen your looping skills with for, forEach, map, filter, looping an object, looping bidimentional arrays, adding conditions to loops, finding an element, and more!

How are the exercises organized?

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

  1. app.js: represents the entry JavaScript file that will be executed by the computer.
  2. README.md: contains exercise instructions.
  3. test.js: contains the testing script for the exercise (you don't have to open this file).

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.
