Nodejs String Padding Left padLeft( pPadChar, pTotalLength )

Method Source Code

/**//www . j a v  a2  s .c  om
 * JS util functions. Mostly augmentations.
*/

/**
 * This function augments the native String object.
 * Returns a left-padded string. Leaves the original string intact.
 * First parameter is the padding character, and it is expected to be exactly 
 * one character long, but using longer paddings should work just as well.
 * Second parameter is the targeted total length of the padded string.
