#Function: pipe()

Applies a sequence of functions to a value, from left to right.

This utility enables function composition in a left-to-right manner. It supports up to 26 chained functions from A through Z.

#Type Param

The initial input value type.

#Type Param

Intermediate and final function return types.

#Param

The initial input value.

#Param

Additional unary functions composing of the previous result.

#Example

import { 
import ResultResult } from '@praha/byethrow';

const 
const result: stringresult = 
import ResultResult.
const pipe: <number, number, number, string>(a: number, ab: (a: number) => number, bc: (b: number) => number, cd: (c: number) => string) => string (+25 overloads)pipe(
  2,
  
x: numberx => 
x: numberx + 1,
  
x: numberx => 
x: numberx * 3,
  
x: numberx => `Result: ${
x: numberx}`
);
// Result: 9
