Collect.js merge() Method

0 0 1 minute read

The merge() method is used to merge the given object into the original collection. If the key of a given object is the same as the collection object then it overwrites the value of the key.

Syntax:

collect(array).merge(object)

Parameters: The collect() method takes one argument that is converted into the collection and then the merge() method is applied to it. The merge() method holds the object as a parameter.

Return Value: This method returns the collection of merged elements.

Module Installation: Install collect.js module using the following command from the root directory of your project:

npm install collect.js

The below example illustrates the merge() method in collect.js:

Example 1: Filename: index.js

Javascript

// Requiring the module 
const collect = require('collect.js'); 
  
let obj = ['Geeks', 'zambiatek']; 
  
// Function call 
const collection = collect(obj); 
  
const merged_val = collection.merge(['Welcome', 'GFG']); 
  
// Printing the merged collection 
console.log(merged_val.all());

Run the index.js file using the following command:

node index.js

Output:

[ 'Geeks', 'zambiatek', 'Welcome', 'GFG' ]

Example 2: Filename: index.js

Javascript

// Requiring the module 
const collect = require('collect.js'); 
  
let obj = [ 
    { 
        name: 'Rahul', 
        dob: '25-10-96', 
    }, 
    { 
        name: 'Aditya', 
        dob: '25-10-96', 
    } 
]; 
  
// Function call 
const collection = collect(obj); 
  
const merged_val = collection.merge({ 
    address: 'Noida', 
    school: 'zambiatek', 
}); 
  
// Printing the merged collection 
console.log(merged_val.all());

Run the index.js file using the following command:

node index.js

Output:

  { name: 'Rahul', dob: '25-10-96' },
