> Split a string on the first occurrence of a given separator
|
||
|
|
||
|
This is similar to [`String#split()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split), but that one splits on all the occurrences, not just the first one.
|
||
|
|
||
|
|
||
|
## Install
|
||
|
|
||
|
```
|
||
|
$ npm install split-on-first
|
||
|
```
|
||
|
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
```js
|
||
|
const splitOnFirst = require('split-on-first');
|
||
|
|
||
|
splitOnFirst('a-b-c', '-');
|
||
|
//=> ['a', 'b-c']
|
||
|
|
||
|
splitOnFirst('key:value:value2', ':');
|
||
|
//=> ['key', 'value:value2']
|
||
|
|
||
|
splitOnFirst('a---b---c', '---');
|
||
|
//=> ['a', 'b---c']
|
||
|
|
||
|
splitOnFirst('a-b-c', '+');
|
||
|
//=> ['a-b-c']
|
||
|
```
|
||
|
