### timeTaken
Measures the time taken by a function to execute.
Use `console.time()` and `console.timeEnd()` to measure the difference between the start and end times to determine how long the callback took to execute.
```js
const timeTaken = callback => {
console.time('timeTaken'); const r = callback();
console.timeEnd('timeTaken'); return r;
};
// timeTaken(() => Math.pow(2, 10)) -> 1024
// (logged): timeTaken: 0.02099609375ms
```
