substringAfter
Return the part of a string after a specified substring.
Installation
npm install @stdlib/string-substring-after
Usage
var substringAfter = require( '@stdlib/string-substring-after' );
substringAfter( str, search[, fromIndex] )
Returns the part of a string after a specified substring.
var str = 'beep boop';
var out = substringAfter( str, 'o' );
// returns 'op'
out = substringAfter( str, ' ' );
// returns 'boop'
By default, the search starts at the beginning of the string. To start searching from a different index, provide a fromIndex
argument:
var str = 'boop baz boop';
var out = substringAfter( str, 'o', 3 );
// returns 'op'
Notes
- If a substring is not present in a provided string, the function returns an empty string.
- If provided an empty substring, the function returns the input string.
- If
fromIndex
is less than0
or greater thanstr.length
, the search starts at index0
andstr.length
, respectively.
Examples
var substringAfter = require( '@stdlib/string-substring-after' );
var str = 'To be, or not to be, that is the question.';
var out = substringAfter( str, ', ' );
// returns 'or not to be, that is the question.'
out = substringAfter( str, 'to be' );
// returns ', that is the question.'
out = substringAfter( str, 'question.' );
// returns ''
out = substringAfter( str, 'xyz' );
// returns ''
out = substringAfter( str, '' );
// returns 'To be, or not to be, that is the question.'
