How to add an array to an object in js

Below I will share with you a js method to add array elements to an object in the simplest way. It has a good reference value and I hope it will be helpful to everyone.

As shown below:

//如题，通常做法就是循环数组，最后在添加length属性，如：

 
var obj = {}; 
 var pushArr = [11,22,33,44,55,66];
 for(var i=0;i<pushArr.length;i++) {
  obj[i] = pushArr[i];
 }
 obj.length = pushArr.length;

 console.log(obj); //{0:11,1:22,2:33,3:44,4:55,5:66,length:6}

Easy method:

//js将数组元素添加到对象中（或 数组转换成对象）有个小技巧：

var obj = {}; 
[].push.apply(obj,[11,22,33,44,55,66]);

console.log(obj); //{0:11,1:22,2:33,3:44,4:55,5:66,length:6}

由于obj是个对象没有像数组的push()方法，所以利用数组的push()以及apply()的特性来将数组作用于push()并修改当前的引用。 有较严重的代码洁癖的患者可以使用这个方法。

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
