babel-plugin-pipe-operator

Overload the pipe operator (|) to provide Elixir/F#/Shell-like behavior

Examples

import { map, filter } from 'lodash';

const array = [1, 2, 3, 4, 5];

const fn = () => {
  const arr = [1, 2, 3] | map(n => n + 1);

  return () => {
    "no pipe";

    arr.map(n => n | 1);
  };
};
