如何在Javascript中组合函数

const compose = (f, g) => (...args) => f(g(...args));

// 示例函数
const addOne = (x) => x + 1;
const multiplyByTwo = (x) => x * 2;
const subtractThree = (x) => x - 3;

// 组合函数
const composedFunction = compose(subtractThree, multiplyByTwo, addOne);

// 使用组合函数
console.log(composedFunction(5)); // 输出: 7

const compose = (...functions) => (args) =>
  functions.reduceRight((arg, fn) => fn(arg), args);

// 示例函数
const addOne = (x) => x + 1;
const multiplyByTwo = (x) => x * 2;
const subtractThree = (x) => x - 3;

// 组合函数
const composedFunction = compose(subtractThree, multiplyByTwo, addOne);

// 使用组合函数
console.log(composedFunction(5)); // 输出: 7
