Problem ​

You need to chain functions left-to-right — applying the first function and passing the result to each subsequent one.

Solution ​

Use pipe(...fns) to create a left-to-right pipeline.

ts
import { pipe } from '@vielzeug/arsenal';

const process = pipe(
  (s: string) => s.trim(),
  (s) => s.toLowerCase(),
  (s) => s.replace(/\s+/g, '-'),
);

process('  Hello World  '); // 'hello-world'

Pitfalls ​

  • Execution is left-to-right: the first function runs first. Use compose for right-to-left.
