// 1. Using the splice method to remove elements from an array

let array = [1, 2, 3, 4, 5];

let index = 2; // Index of the element to be removed

let count = 2; // Number of elements to be removed

array.splice(index, count);

console.log(array); // Output: [1, 2, 5]

// 2. Using the slice method to extract a portion of an array

let originalArray = [1, 2, 3, 4, 5];

let newArray = originalArray.slice(2); // Extract elements starting from index 2 till the end

console.log(newArray); // Output: [3, 4, 5]
