Collect.js replaceRecursive() Method

The replaceRecursive() method is similar to the replace() method but it works recursively and this method will recurse into arrays and the inner values are treated with the same replacement process.

Syntax:

collect(array).replaceRecursive(object)

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

Return Value: This method returns the collection elements with replaced value.

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 replaceRecursive() method in collect.js:

Example 1: Filename: index.js

Javascript

// Requiring the module
const collect = require('collect.js');

// Creating collection object
const collection = collect([
    ['Geeks', 'GFG', 'GeeksforGeeks'],
    ['Welcome', 'to', 'GeeksforGeeks']
]);

// Function call
const replaced = collection.replaceRecursive(
    { 0: 'Hello', 3: 'Welcome' });

// Printing values
console.log(replaced.all());

Run the index.js file using the following command:

node index.js

Output:

{
  '0': 'Hello',
  '1': { '0': 'Welcome', '1': 'to', '2': 'GeeksforGeeks' },
  '3': 'Welcome'
}

Example 2: Filename: index.js

Javascript

// Requiring the module
const collect = require('collect.js');

const obj = [
    {
        name: 'Rahul',
        marks: 88
    },
    {
        name: 'Aditya',
        marks: 78
    },
    {
        name: 'Abhishek',
        marks: 87
    }
];

// Creating collection object
const collection = collect(obj);

// Function call
const replaced = collection.replaceRecursive(
    { 0: 'Welcome', 3: 'GeeksforGeeks' });

// Printing values
console.log(replaced.all());

Run the index.js file using the following command:

node index.js

Output:

{
  '0': 'Welcome',
  '1': { name: 'Aditya', marks: 78 },
  '2': { name: 'Abhishek', marks: 87 },
  '3': 'GeeksforGeeks'
}
