### Measure time taken by function ### Measure time taken by function
Use `performance.now()` to get start and end time for the function, `console.log()` the time taken. Use `performance.now()` to get start and end time for the function, `console.log()` the time taken.
First argument is the function name, subsequent arguments are passed to the function. Pass a callback function as the argument.
```js ```js
const timeTaken = (func,...args) => { const timeTaken = callback => {
var t0 = performance.now(), r = func(...args); const t0 = performance.now(), r = callback();
console.log(performance.now() - t0); console.log(performance.now() - t0);
return r; return r;
} }
// timeTaken(Math.pow, 2, 10) -> 1024 (0.010000000009313226 logged in console) // timeTaken(() => Math.pow(2, 10)) -> 1024 (0.010000000009313226 logged in console)
