code repetition trim() stripWhitespace()

[fernandolguevara]

both functions do the same thing

function trim(value) {
  return isString(value) ? value.replace(/^\s*/, '').replace(/\s*$/, '') : value;
}

var START_SPACE = /^\s*/;
var END_SPACE = /\s*$/;
function stripWhitespace(str) {
  return isString(str) ? str.replace(START_SPACE, '').replace(END_SPACE, '') : str;
}
