This article mainly introduces how to convert a pseudo array into an array through js. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

Method 1:

Traverse the pseudo array and push the value into an empty array

Method 2: Use the slice method of the array, which returns an array. Use call or apply to point to the pseudo array

var arr = [].slice.call(arguments);或var arr = Array.propotype.slice.call(arguments);
alert(Array.isArray(arr));

Method 3: New method for arrays in ES6 Array.from()

function testArray(){     
var arg = Array.from(arguments);
     arg.push(7);
     console.log(arg);//1,2,3,4,7 }
 testArray(1,2,3,4);
