## Introduction
|
||
|
|
|
||
|
|
Like `String.prototype.match` if it only checked the regex at the given index instead of searching the entire string.
|
||
|
|
|
||
|
|
```js
|
||
|
|
matchAt(/world/, 'hello world', 6); // ['world']
|
||
|
|
matchAt(/world/, 'hello world', 0); // null
|
||
|
|
```
|
||
|
|
|
||
|
|
Almost like `'hello world'.slice(i).match(/^world/)` except the resulting match object's `.index` property corresponds to the original string, and it doesn't actually slice the string. Most engines optimize taking a substring so this probably isn't particularly valuable in practice, but it was an entertaining exercise and could be useful if you reminisce about these semantics.
