The purpose of string padding is to add characters to a string, so it reaches a specific length.

padStart() can be used to add characters at the beginning of a string.

padStart(targetLength [, padString])

Sample usage:

padStart()
‘test’.padStart(4) ‘test’
‘test’.padStart(5) ‘ test’
‘test’.padStart(8) ‘    test’
‘test’.padStart(8, ‘abcd’) ‘abcdtest’
