JS Dynamic Add Object

JS array, string, object operation is an indispensable part of implementing some functions.

In general, JS array and string dynamic add up more convenient, have their own methods, the array of push (), the string directly with the plus sign and so on. But the JS object will need a little work to add dynamically.

Now I've written two ways to add objects dynamically

First Kind

    function toObj1 (key,val) {           var data = {};             = val;            return data;       }        var obj1 = toObj1 (' name ', ' Nurdun ');       Console.log (obj1);

The second Kind

    function ToObj2 (key,val) {           var data = {[Key]:val};            return data;       }        var obj2 = toObj2 (' name ', ' Nurdun ');       Console.log (OBJ2);

Here are the applications of these two methods

First set two arrays, one for key, one for Val

var keyarr= ["Name", "Age", "job"var valarr = ["Nurdun", 3, "front-end"]

Here are two types of dynamically added objects

    function fn (Keyarr,valarr) {           var  data = {};             for (i = 0;i<keyarr.length;i++) {               var  key = keyarr[i];                var  val = Valarr[i];                = val;           }            return data;       }         var op = fn (keyarr,valarr);       Console.log (OP);

The following method is the previous key will be overwritten by the following key

    function Fun (Keyarr,valarr) {           var  data = {};             for (i = 0;i<keyarr.length;i++) {               var  key = keyarr[i];                var  val = Valarr[i];                = {[Key]:val};           }            return data;       }        var op1 = Fun (keyarr,valarr);       Console.log (OP1);
