How 2 JS

Instructions

Hello and welcome to the JS piscine, first you will have to learn to execute javascript.

Being a special child, JS can run in different runtime, what you can do with it greatly depend of your runtime.

Luckily you don't need to install anything for that since all you need is a web browser.

Main runtime for executing JS are: any web browser, NodeJS and Deno.

Let's make a hello world:

# first we create the javascript file
echo "console.log('Hello World')" > how-2-js.js

# To run JS in your browser you need to import it from an HTML page:
echo '<script type="module" src="how-2-js.js"></script>' > index.html

# Finally let's create a simple web server
&>/dev/null python3 -m http.server &

# Now open your browser at the specified port
xdg-open 'http://localhost:8000'

xdg-open find your default application for the given argument on mac it's just open and it's start on windows

You can now open your web browser console (ctrl+shift+i) and you should see your hello world.

The console is a very handy place to test code and explore how the language works, don't be shy and play in it !

Great ! you are all set, if you want to re-execute your script, just refresh.

You now just have to create a repository named ((ROOT)), which will hold all your solutions for this piscine and just add your 2 generated files to it, we will start slow for now... 🐢
