Tap

A function that displays the content of a variable or function return on the console without compromising the flow.

Javascript:

  function tap(x, fn) {
    console.log(fn(x));
    return x;
  }

Typescript:

function tap<T>(x: T, fn: (x: T) => unknown = (x) => x): T {
  console.log(fn(x));
  return x;
}
