# Timing Processes
|
|
|
|
If you want to time a process, you can use the `console.time()` and
|
|
`console.timeEnd()` utilities specified by the `console` Web API. Invoking
|
|
`console.time()` with a label starts a named timer. You can then run the
|
|
process you want to time. Then invoke `console.timeEnd()` with the same
|
|
label to terminate the timer and see how long the process took.
|
|
|
|
```javascript
|
|
console.time('sorting');
|
|
[11,10,9,8,7,6,5,4,3,2,1].sort();
|
|
console.timeEnd('sorting');
|
|
> sorting: 0.278ms
|
|
|
|
console.time('console logging');
|
|
console.log('logging to the console');
|
|
console.timeEnd('console logging');
|
|
> logging to the console
|
|
> console logging: 0.311ms
|
|
|
|
console.time('adding'); 1 + 1; console.timeEnd('adding');
|
|
> adding: 0.006ms
|
|
```
|
|
|
|
These functions are implemented in most modern browsers.

|
|
docs](https://developer.mozilla.org/en-US/docs/Web/API/Console/time) for
|
|
more details.
