Generator in JavaScript

Generator

生成器函数是一种特殊的函数，它可以通过 yield 关键字来暂停和恢复执行。生成器函数返回一个生成器对象，该对象可以用于遍历生成器函数的值。

function* generator() {
  yield 1;
  yield 2;
  yield 3;
}


const gen = generator();


console.log(gen.next()); // { value: 1, done: false }
console.log(gen.next()); // { value: 2, done: false }
console.log(gen.next()); // { value: 3, done: false }
console.log(gen.next()); // { value: undefined, done: true }
