One way to start/stop is like this
var requestId;

function loop(time) {
requestId = undefined;

...
// do stuff
...

start();
}

function start() {
if (!requestId) {
requestId = window.requestAnimationFrame(loop);
}
}

function stop() {
if (requestId) {
Working example:
const timeElem = document.querySelector("#time");
var requestId;

function loop(time) {
requestId = undefined;

doStuff(time)
start();
}

function start() {
if (!requestId) {
requestId = window.requestAnimationFrame(loop);
}
}

function stop() {
if (requestId) {
