Learn the basics about functions in #"auto">

  • Basic theory about functions in JavaScript.
  • Learn the syntax on how to create functions.
  • How to call functions.
  • What are function parameters and the return statement.
  • How to create traditional, arrow and anonymous functions.
  • 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.

    One click installation (recommended):

    You can open these exercises in just a few seconds by clicking:Open in Codespaces (recommended) orOpen in Gitpod.

    Once you have VSCode open, if exercises don't run automatically you can try typing on your terminal:$ learnpack start

    Local Installation

    Clone the repository in your local environment and follow the steps below:

    1. Install LearnPack, the package manager for learning tutorials and the node compiler plugin for LearnPack, make sure you also have node.js 14+:
    $ npm i learnpack -g$ learnpack plugins:install learnpack-node
    1. Download this particular exercise using LearnPack andcd into the folder:
    $ learnpack download javascript-functions-exercises-tutorial$cd javascript-functions-exercises-tutorial

    Note: Once you finish downloading, you will find an "exercises" folder that contains all the exercises within.

    1. Start the tutorial/exercises by running the following command at the same level where your learn.json file is:
    $ npm i jest@24.8.0 -g$ learnpack start

    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.
