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' }
