Function tap

Applies a function sideEffect to the input, then returns the input. The primary use case for tap is debugging values in the middle of a pipe or flow chain.

Example

import { pipe, tap } from "flurp";
import * as N from "flurp/number";

pipe(
  5,
  N.multiply(2),
  tap(console.log),    // prints 10 to the console, passes 10 on to the next function
  N.multiply(2)
);                     // 20
