How Can One Retrieve The First N Elements From An Array In JavaScript?

To get the first N number of elements from an array in JavaScript, you can use the slice() method.

Here’s an example:

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const N = 5;

const firstNElements = array.slice(0, N);
console.log(firstNElements); // Output: [1, 2, 3, 4, 5]

In this example, we define an array array containing elements from 1 to 10. We also define a variable N representing the number of elements we want to get. The slice() method is then used on the array specifying the start index as 0 and the end index as N. This will create a new array firstNElements containing the first N elements from the original array. Finally, we log the firstNElements to the console.
