In javascript, how to get the entire array removing the first and last elements from it?

To remove the first and last elements of an array in JavaScript, you can use the `slice()` method. The `slice()` method returns a new array containing a portion of the original array, starting from the specified start index and ending at the specified end index.

Here's an example code that demonstrates how to remove the first and last elements of an array in JavaScript using the `slice()` method:

const arr = [1, 2, 3, 4, 5];

const newArr = arr.slice(1, arr.length - 1);

console.log(newArr); // Output: [2, 3, 4]

In this example, we first create an array `arr` containing five elements. Then we use the `slice()` method to create a new array `newArr` that starts from the second element (`1`) and ends at the second-to-last element (`arr.length - 1`).

This effectively removes the first and last elements from the `arr` array. Finally, we log the `newArr` array to the console. The output is `[2, 3, 4]`, which is the entire array with the first and last elements removed.
