Pad in javascript

I needed  a function that add zeros to the right in javascript and also one that accepts other chars, so I made this one.

 


rightPad: function(howMany, symbol) {
symbol = symbol || '';
var init = '0.';
var zero = '';
for (var i = 0; i < howMany; i++) {
zero = zero + '0';
}
return init + zero + (symbol === '' ? '' : ' ' + symbol);
},

rightPad(5, "%";);

Simple.
