Have also a look at "Animation with requestAnimationFrame".
This example has been provided by user Cleonis.
<button onclick="play()">play</button> <button onclick="resetAnimation()">reset</button>// Define the id of your board in BOARDID
const board = JXG.JSXGraph.initBoard(BOARDID, {
boundingbox: [-1.5, 1.5, 1.5, -1.5],
keepaspectratio: true,
axis: true
});
var isPlaying = false;
var starttime = 0;
var timeElapsed = 0;
var interval;
var p = board.create('point',
[() => Math.cos(timeElapsed), () => Math.sin(timeElapsed)]
);
function playing() {
timeElapsed = (Date.now() - starttime) / 1000;
board.update();
}
function play() {
if (!isPlaying) {
starttime = Date.now();
isPlaying = true;
interval = setInterval(playing, 50);
}
}
function resetAnimation() {
clearInterval(interval);
timeElapsed = 0;
isPlaying = false;
board.update();
}
