### 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;
|
|
};
|
|
```
|
|
|
|
```js
|
|
timeTaken(() => Math.pow(2, 10)); // 1024
|
|
// (logged): timeTaken: 0.02099609375ms
|
|
```
