### Measure time taken by function
|
|
|
|
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.
|
|
|
|
```js
|
|
const timeTaken = (func,...args) => {
|
|
var t0 = performance.now(), r = func(...args);
|
|
console.log(performance.now() - t0);
|
|
return r;
|
|
}
|
|
// timeTaken(Math.pow, 2, 10) -> 1024 (0.010000000009313226 logged in console)
|
|
```
