这篇文章主要介绍了JavaScript遍历数组的方法代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
for循环
let arr=["A","B","C","D","E","F"];
for(let i=0;i<arr.length;i++){
console.log(arr[i]);
}
for...of
遍历出数组中的每个值
let arr=["A","B","C","D","E","F"];
for(let item of arr){
console.log(item);
}
//A B C D E F
for..in
遍历出数组中每个值的下标
let arr=["A","B","D","E","F"];
for(let item in arr){
console.log(item);
}
//0 1 2 3 4 5
ES6新增for...of的用法
遍历出数组中每个值的键（下标） arr.keys()
let arr=["A","B","C","D","E","F"];
for(let item of arr.keys()){
console.log(item);
}
//0 1 2 3 4 5
遍历出数组中的每个值 arr.values()
let arr=["A","B","C","D","E","F"];
for(let item of arr.values()){
console.log(item);
}
//A B C D E F
遍历出数组中的每个值，以及每个值对应的下标 arr.entries()
let arr=["A","B","C","D","E","F"];
for(let item of arr.entries()){
console.log(item);
}
/**
[ 0, 'A' ]
[ 1, 'B' ]
[ 2, 'C' ]
[ 3, 'D' ]
[ 4, 'E' ]
[ 5, 'F' ]
**/
