Collect.js | flip() function

0 0 1 minute read

The flip() function swaps the key with its corresponding value. In JavaScript, the array is first converted to a collection and then the function is applied to the collection.

Syntax:

data.flip()

Parameters: This function does not accept any parameter.

Return Value: Returns by flipping the collection.

Below examples illustrate the flip() function in collect.js
Example 1: Here in this example, we take a collection and then using the flip() function we flip the key and the item in collection.

Javascript

// It is used to import collect.js library 
const collect = require('collect.js'); 
  
const collection = collect({ 
  name: 'Jhon ', 
  number: 000-555, 
}); 
  
console.log(collection.flip());

Output:

Collection { items: { 'Jhon ': 'name', '-555': 'number' } }

Example 2:

Javascript

// It is used to import collect.js library 
const collect = require('collect.js'); 
  
const collection = collect({ 
    address : ['311-Street', 'US'], 
    pin : 2546, 
    number : 9898-585-598,  
}); 
  
const X  = collection.flip(); 
console.log(X.all());

Output:

{ '2546': 'pin', '8715': 'number', '311-Street,US': 'address' }
