Approach to get first N number of elements

We will create an array containing some values using the react class component and from the user input, we will display n number of elements on the page. We can use array.slice method to get the first N numbers from the array.

Syntax:

array.slice(0, n);

Note: The slice function on arrays returns a shallow copy of the array, and does not modify the original array. And if N is larger than the size of the array then it won’t through any error and returns the whole array itself.

To get the first N number of elements from an array using React JS simply means to display the N number of elements of the array.
