006

Format a number as a three-digit, zero-padded string — the shape used by many numeric codes (ISO-style IDs, ticket numbers, fixed-width export formats).

const code3 = require('006');

code3(6);      // '006'
code3('42');   // '042'
code3(12345);  // '12345'  (longer input returned as-is)

Zero dependencies. TypeScript types included.
