You're thinking of left-pad.
npm install alt-left-padalt-left-pad is an alternative left-pad implementation.
"alt-left" doesn't exist, what even would alt-left-pad do??
Glad you asked! It left-pads strings just like left-pad, but not as quickly.
It does multi-character pads, and if it adds any padding, it truncates (on the left) to fit the given length.
