What would you like to do?
A CPU intensive operation. Use to test imitate blocking code, test WebWorkers etc.
function mySlowFunction(baseNumber) {
console.time('mySlowFunction');
let result = 0;
for (var i = Math.pow(baseNumber, 7); i >= 0; i--) {
result += Math.atan(i) * Math.tan(i);
};
console.timeEnd('mySlowFunction');
}
mySlowFunction(8); // higher number => more iterations => slower

Another function with similar functionality seen elsewhere:

function mySlowFunction(blockTime: number) {
	console.time('mySlowFunction');
        const now = performance.now();
	while(performance.now() - now < blockTime) {}
	console.timeEnd('mySlowFunction');
}

mySlowFunction(1000); //millisecond
