Right pad a string.
$ npm install utils-right-pad-string
var rpad = require( 'utils-right-pad-string' );
Right pads a string
such that the padded string
has a length
of at least len
.
var str = rpad( 'a', 5 );
// returns 'a '
By default, an input string
is padded with spaces
. To pad with a different character or sequence of characters, provide a pad
string.
var str = rpad( 'beep', 10, 'p' );
// returns 'beeppppppp'
str = rpad( 'beep', 12, 'boop' );
// returns 'beepboopboop'
An output string
is not guaranteed to have a length of exactly len
, but to have a length
of at least len
. To generate a padded string
having a length
equal to len
var str = rpad( 'beep', 10, 'boop' );
// returns 'beepboopboop' => length 12
str = str.substring( 0, 10 );
// returns 'beepboopbo' => length 10
var round = require( 'math-round' );
var rpad = require( 'utils-right-pad-string' );
var str = 'beep';
var n;
var i;
for ( i = 0; i < 100; i++ ) {
n = round( Math.random()*10 ) + str.length;
console.log( rpad( str, n, 'p' ) );
}
