What is compose-function?

The compose-function npm package provides utility functions for function composition, allowing you to combine multiple functions into a single function. This is particularly useful in functional programming paradigms where you want to create complex operations by combining simpler ones.

What are compose-function's main functionalities?

compose

The `compose` function allows you to combine multiple functions into a single function. In this example, `addThenMultiply` first adds 1 to the input and then multiplies the result by 2.

const compose = require('compose-function');

const add = x => x + 1;
const multiply = x => x * 2;

const addThenMultiply = compose(multiply, add);
console.log(addThenMultiply(5)); // Output: 12

pipe

The `pipe` function is similar to `compose` but applies functions from left to right. In this example, `multiplyThenAdd` first multiplies the input by 2 and then adds 1.

const { pipe } = require('compose-function');

const add = x => x + 1;
const multiply = x => x * 2;

const multiplyThenAdd = pipe(add, multiply);
console.log(multiplyThenAdd(5)); // Output: 11
