Python has str.ljust [1] (and str.rjust [2]):

> Return the string left justified in a string of length width. Padding is done using the specified fillchar (default is an ASCII space). The original string is returned if width is less than or equal to len(s).

Ruby and PHP both have string padding functions. So does Swift. (edit: and as Macha points out, C and any language with printf functionality, like Perl.) It’s not that uncommon.

(I was going to joke that TRS-80 BASIC had it circa 1979, but it turns out that it would be a two-step operation: Python’s str.ljust(40) would become LEFT$(STRING$(40, " "),40) .)

C has it in their standard library, basically forever. See the list of specifiers to printf. C! If it fits into the C standard library, it's not bloating the Javascript standard library.
