let setInterval: (unit => unit, int) => intervalId;

Repeatedly executes a callback with a specified interval (in milliseconds) between calls. Returns a Js.Global.intervalId that can be passed to Js.Global.clearInterval to cancel the timeout.

let setTimeout: (unit => unit, int) => timeoutId;

Execute a callback after a specified delay (in milliseconds). Returns a Js.Global.timeoutId that can be passed to Js.Global.clearTimeout to cancel the timeout.
