# split-on-first [](https://travis-ci.com/sindresorhus/split-on-first)

|
> 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.
