How to read a local text file?

Question

I’m trying to write a simple text file reader by creating a function that takes in the file’s path and converts each line of text into a char array, but it’s not working.

How to read a local file?

By using this you will load a file by loadText() then JS will asynchronously wait until the file is read and loaded after that it will execture readText() function allowing you to continue with your normal JS logic (you can also write a try catch block on the loadText() function in the case any error arises) but for this example I keep it at minimal.

async function loadText(url) {
    text = await fetch(url);
    //awaits for text.text() prop 
    //and then sends it to readText()
    readText(await text.text());
}

function readText(text){
    //here you can continue with your JS normal logic
    console.log(text);
}

loadText('test.txt');
