JavaScript Fetch API
Examples
fetch(file)
.then(x => x.text())
.then(y => myDisplay(y));
Fetch is based on async and await. The example might be easier to understand like this:
async function getText(file) {
let x = await fetch(file);
let y = await x.text();
myDisplay(y);
}
Use understandable names instead of x and y:
async function getText(file) {
let myObject = await fetch(file);
let myText = await myObject.text();
myDisplay(myText);
}
