The value to be padded
The length of the resulting string once the current str has been padded. If the value is less than str.length, then str is returned as-is.
OptionalpadString: stringThe string to pad the current str with. If padString is too long to stay within the targetLength, it will be truncated from the end. The default value is the unicode "space" character (U+0020).
The
strPadStart()method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string. This will use any native implementation if available, but will fall back to the provided polyfill for runtimes that don't support padStart
