JavaScript 嵌套内部 for 循环不起作用

Question

我想将 bobsFollower 数组和 tinasFollower 数组中的公共(public)字符串存储在 mutualFollowers 数组中。

const bobsFollowers = ['vinit','vidyesh','bipin','shobhana'];
const tinasFollowers = ['vinit','vidyesh','manish'];
const mutualFollowers = [];
for (let i = 0; i < bobsFollowers.length; i++){
  for (let j = 0; j < tinasFollowers.lenght; j++){
    if (bobsFollowers[i] === tinasFollowers[j]){
      mutualFollowers.push(tinasFollowers[j]);
    }     
  }
};
console.log(mutualFollowers);

未执行内部 for 循环

Answer 1

您在内循环中出现拼写错误:您将 length 错误地输入为 lenght!

const bobsFollowers = ['vinit','vidyesh','bipin','shobhana'];
const tinasFollowers = ['vinit','vidyesh','manish'];
const mutualFollowers = [];
for (let i = 0; i < bobsFollowers.length; i++){
  for (let j = 0; j < tinasFollowers.length; j++){
    if (bobsFollowers[i] === tinasFollowers[j]){
      mutualFollowers.push(tinasFollowers[j]);
    }     
  }
};
console.log(mutualFollowers);
