Use Javascript to open a directory?

How would I use JS to open testing.txt and read what is in it?
(I am using Javascript by having a .html file and using a <script> tag.)

Easy! Make an HTTP request! (Note you won't be able to write)

fetch("/myfile.txt", { method: "GET" }).then(e => e.text()).then(console.log)

This is what happened:

nooo you can't use it like that @isaiah08

ugggh ig you don't know what promises are. You see, it takes some time to load the file, and JS doesn't like that, so it returns something called a promise, which will get resolved later on. What you want is:

(async () => {

var x = await fetch("/u.txt", { method: "GET" }).then(e => e.text())
document.getElementById("id").innerHTML = x;

})

Also, you forgot to set the type of the output lol

Thank you! @Coder100

No problem! @isaiah08

You would use the Javascript FS module, but it can't be used in an HTML, CSS, JS repl, it'll have to be used on a NODEJS repl

@mamamia5x no they don't, they can just make an HTTP request

Ur right j*r** (not bad word, his name) @Coder100
