Repeat
Repeat a string a specified number of times and return the concatenated result.
Usage
var repeat = require( '@stdlib/string/repeat' );
repeat( str, n )
Repeats a string n
times and returns the concatenated result.
var str = repeat( 'a', 5 );
// returns 'aaaaa'
str = repeat( '', 100 );
// returns ''
str = repeat( 'beep', 0 );
// returns ''
Examples
var round = require( '@stdlib/math/base/special/round' );
var randu = require( '@stdlib/random/base/randu' );
var repeat = require( '@stdlib/string/repeat' );
var str = 'beep';
var n;
var i;
for ( i = 0; i < 100; i++ ) {
n = round( randu()*3.0 );
console.log( repeat( str, n ) );
}
CLI
Usage
Usage: repstr [options] [<string>] --n <repeats>
Options:
-h, --help Print this message.
-V, --version Print the package version.
--n repeats Number of repetitions.
Notes
-
If the split separator is a regular expression, ensure that the
split
option is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'beep\nboop' | repstr --n 3 --split /\r?\n/ # Escaped... $ echo -n $'beep\nboop' | repstr --n 3 --split /\\r?\\n/
-
The implementation ignores trailing delimiters.
Examples
$ repstr beep --n 5
beepbeepbeepbeepbeep
To use as a standard stream,
$ echo -n $'ab' | repstr --n 3
ababab
By default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split
option.
$ echo -n $'beep\tboop' | repstr --n 3 --split '\t'
beepbeepbeep
boopboopboop
