Merging Two Arrays of Objects: A JavaScript Solution
Merging arrays of objects in JavaScript can be a common task. Here, we explore a simple yet efficient method for achieving this using the intrinsic function Array.prototype.push.apply().
Consider the example scenario:
var arr1 = [{name: "lang", value: "English"},{name: "age", value: "18"}]; var arr2 = [{name : "childs", value: '5'}, {name: "lang", value: "German"}];
Our goal is to merge these two arrays into a single array, called arr3, with the following content:
var arr3 = [{name: "lang", value: "German"},{name: "age", value: "18"},{name : "childs", value: '5'}];
Using jQuery's $.extend() is not suitable here, as it does not provide the desired output. Instead, we employ the following code:
Array.prototype.push.apply(arr1,arr2); console.log(arr1);
This code essentially appends the elements of arr2 to the end of arr1. The result is a single array containing the merged objects, with duplicate "lang" objects being replaced by the latter value.
The output obtained is:
[{"name":"lang","value":"English"},{"name":"age","value":"18"},{"name":"childs","value":"5"},{"name":"lang","value":"German"}]
This output matches the desired array arr3, effectively merging the original two arrays of objects.
