rtrimN

Trim n characters from the end of a string.

Installation

npm install @stdlib/string-right-trim-n

Usage

var rtrimN = require( '@stdlib/string-right-trim-n' );

rtrimN( str, n[, chars] )

Trims n characters from the end of a string.

var str = '  foo  ';
var out = rtrimN( str, str.length );
// returns '  foo'

out = rtrimN( str, 1 );
// returns '  foo '

By default, the function trims whitespace characters. To trim a different set of characters instead, provide a string or an array of characters to trim:

var str = '🐶🐶🐶 Animals 🐶🐶🐶';
var out = rtrimN( str, str.length, [ '🐶', ' ' ] );
// returns '🐶🐶🐶 Animals'

out = rtrimN( str, str.length, '🐶 ' );
// returns '🐶🐶🐶 Animals'

Examples

var rtrimN = require( '@stdlib/string-right-trim-n' );

var out = rtrimN( '   Whitespace   ', 3 );
// returns '   Whitespace'

out = rtrimN( '\t\t\tTabs\t\t\t', 2 );
// returns '\t\t\tTabs\t'

out = rtrimN( '~~~CUSTOM~~~', 3, '~' );
// returns '~~~CUSTOM'
