Last Updated : 18 Aug, 2020

With the help of _.iterators.List() method, we can get the iterator which when called up gives the next value of the List by using this method.

Syntax :

_.iterators.List(array:Array)

Parameters value: This method accepts a single parameter as mentioned above and described below:

array: It holds the array where the method will be applied.

Return: Return the iterator for a List.

Example 1: In this example, we can see that by using _.iterators.List(array:Array) method, we are able to get the iterator which is invoked every time we call the iterator and return values of the List when called.

JavaScript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');

var gfg = _.iterators.List(["Geeks", "for", "Geeks"]);

for(var i = 0; i < 3; i++) {
    console.log(gfg());
}

Output :

Geeks
for
Geeks

Example 2 :

JavaScript

// Defining underscore contrib variable 
var _ = require('underscore-contrib');

var gfg = _.iterators.List(["A", "B", "C", "D", "E"]);

for(var i = 0; i < 3; i++) {
    console.log(gfg());
}

Output :

A
B
C
