Getting Started

Import pipe from package and just compose your functions with it.

import pipe from '@bitty/pipe';

const resolveToNumber = pipe(
  (value: unknown) => typeof value === 'number' ? value : parseFloat(value),
  (value: number) => Number.isNaN(value) ? 0 : value,
);

resolveToNumber('12389');
//=> 12389

The first pipe argument is an arity N function, so you can receive more than one argument in the composition.

import pipe from '@bitty/pipe';

const fromTextToWords = (text: string, wordsToIgnore: string[] = []) =>
  text
    .trim()
    .split(/\s+/)
    .filter((word) => !wordsToIgnore.includes(word));

const formatToInitials = pipe(
  fromTextToWords,
  (words) => words.map((word) => word.charAt(0)),
  (initials) => initials.join('').toUpperCase(),
);

formatToInitials('abraão  william de santana ', ['de']);
//=> "AWS"
