To install Node.js on iOS, you need to use iSH. You can find instructions on how to install iSH here. Once you have iSH installed, you can install Node.js like so:
apk add nodejs
To check what version of Node.js is installed you can use the command:
node --version
Node gives you a way to run JavaScript code without having to use a web page.
In a command line you can then do things like node my_script.js. This is good because then you wont need to worry about html and browsers and devtools and all that stuff. You can just save your script, open a terminal, cd into the right place and then use node to execute it whenever you want.
You don’t need to hand this in or anything. It’s just for you to check that stuff is running correctly.
Use Koder to create a new file.
Inside the file, type in
console.log("Winning")
Now save the file. You can just call it winning.js or something. The .js at the end is really important. Whenever you save a JavaScript file you need to add .js to the end.
You can open up iSH and use the cd command to navigate to the folder where you saved your file. Then you can use the ls command to check that your file is there.
Now if you type in node winning.js your code will run.
If you get an error like
internal/modules/cjs/loader.js:834
throw err;
^
Error: Cannot find module '/home/sheena/workspace/ACN-syllabus/winning.js'

}
it just means you saved your file somewhere unexpected. You can use the pwd command to check where you are. Then you can use the cd command to navigate to the right place.
node [the path you just copied]
For example this is how it would look on my computer:
node /home/sheena/workspace/temp/winning.js
