Collect.js | forget() Function

The forget() function as the name suggest forgets/remove an item from the collection using its key.  In JavaScript, the array is first converted to a collection and then the function is applied to the collection.
Syntax: 

data.forget('key')

Parameters: This function accept a single parameter as mentioned above and described below:

• Key: This parameter holds the key name that define the value of that key.

Return value: Return the collection except the key's value that was mentioned.

Below examples illustrate the forget() function in collect.js
Example 1: Here in this example, we take a collection and then using the forget() function we return the collection without the key element we forget.

// It is used to import collect.js library
const collect = require('collect.js');

const collection = collect({
  name: 'Jhon',
  Roll: 7,
});

collection.forget('Roll');

console.log(collection.all());

Output: 

{ name: 'Jhon' }

Example 2: Same thing we have done here as above example.

// It is used to import collect.js library
const collect = require('collect.js');

const collection = collect({
  Address : '253 Street , California',
  pincode : '0987'
});

collection.forget('Address');

console.log(collection.all());

Output: 

{ pincode: '0987' }
