What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A tiny JavaScript utility for left-padding strings to a given length, famous from the 2016 npm ecosystem incident. It is deprecated since native String.prototype.padStart covers the same functionality.
Use cases
- pad strings with leading characters in old Node.js versions
- zero-pad numbers like IDs or dates
- align text output in CLI tools
- maintain legacy code that depends on left-pad
When to choose
- you are on a very old JavaScript environment without String.prototype.padStart
- you must keep an existing dependency working in legacy code
When to avoid
- starting any new project - use the built-in String.prototype.padStart instead
- you need Unicode-aware padding beyond the BMP plane
