pipe

The pipe() method chains up to 15 synchronous functions, passing the output of one as the input of the next. It returns the last computed value and stays fully typed at each step.

Interactive example

Syntax

function pipe<Input, Output1>(
	input: Input,
	pipe1: (input: Input) => Output1
): Output1

function pipe<Input, Output1, Output2>(
	input: Input,
	pipe1: (input: Input) => Output1,
	pipe2: (input: Output1) => Output2
): Output2

// ... additional overloads (up to 15 functions)

Parameters

• input : The initial value to transform.
• pipe1, pipe2, ... : Functions applied sequentially. Each receives the output of the previous one.

Return value

The value returned by the last function in the chain, with precise typing based on the chaining.
