Window

The Window interface represents a window containing a DOM document; the document property points to the DOM document loaded in that window.

The Window interface is home to a variety of functions, namespaces, objects, and constructors which are not necessarily directly associated with the concept of a user interface window. However, the Window interface is a suitable place to include these items that need to be globally available. Many of these are documented in the JavaScript Reference and the DOM Reference.

fetch()

See: requests.md

setInterval()

The setInterval() method, offered on the Window and Worker interfaces, repeatedly calls a function or executes a code snippet, with a fixed time delay between each call.

scope.setInterval(func, delay, [arg1, arg2, ...]);

// logs a random number to the console every 1000ms
setInterval(() => {
  let randomNum = Math.floor(Math.random() * 100);
  console.log(randomNum);
}, 1000);

setTimeout()

The setTimeout() method, offered on the Window and Worker interfaces, sets a timer which executes a function or specified piece of code once the timer expires.

scope.setTimeout(func[, delay, arg1, arg2, ...]);

// logs a random number to the console after 5 seconds
setTimeout(() => {
  let randomNum = Math.floor(Math.random() * 100);
  console.log(randomNum);
}, 5000);
