for...of语句创建一个循环来迭代可迭代的对象。在 ES6 中引入的for...of循环,以替代for...in和forEach(),并支持新的迭代协议。for...of允许你遍历 Arrays(数组), Strings(字符串), Maps(映射), Sets(集合)等可迭代的数据结构等。 语法 for(variable ofiterable) { statement } variable:每个迭代的属性...
for-in访问继承的属性确实有一个用例:遍历对象的所有可枚举属性。但是即使在这里,我还是希望手动遍历原型链,因为您拥有更多控制权。 三、数组的forEach方法 考虑到两者for都不for-in是特别适合循环遍历数组,ECMAScript 5中引入了一个辅助方法Array.prototype.forEach(): arr.forEach((elem, index) =>{ console.l...
