Last Updated :

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
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
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' }
