ES6 | Merge Objects
We can merge two JavaScript Objects in ES6 by using the two popular methods. The methods are listed below:
- Object.assign() method
- Object spread syntax method
Both the methods are described below with the proper example:
Method 1: To merge two object we will use Object.assign() method.
- Syntax:
Object.assign(target, ...sources)
- Example:
javascript
<script> // An Object var obj1 = {1 : "Geeks", 2: "for"}; var obj2 = { 3 : "Geeks"}; // Using Object.assign() Object.assign(obj1, obj2); // Printing object for (var key of Object.keys(obj1)) { document.write(key + " => " + obj1[key] + "</br>") }</script> |
- Output:
1 => Geeks 2 => for 3 => Geeks
Method 2: In this method, to merge two object we will use Object spread syntax.
- Syntax:
var objClone = { ...obj };- Example:
javascript
<script> // An Object var obj1 = {1 : "Geeks", 2: "for"}; var obj2 = { 3 : "Geeks"}; // Using Object spread syntax var obj = {...obj1, ...obj2}; // Printing object for (var key of Object.keys(obj)) { document.write(key + " => " + obj[key] + "</br>") }</script> |
- Output:
1 => Geeks 2 => for 3 => Geeks
