What is the purpose of the array slice method

The slice() method in JavaScript is used to extract a section of an array, returning a new array containing the selected elements. It does not modify the original array. The method takes two arguments:

• start: The index at which extraction begins (inclusive).
• end (optional): The index before which to end extraction (exclusive). If omitted, extraction continues to the end of the array.

You can also use negative indices, which count from the end of the array.

Examples:

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

let arrayIntegers1 = arrayIntegers.slice(0, 2);    // [1, 2]
let arrayIntegers2 = arrayIntegers.slice(2, 3);    // [3]
let arrayIntegers3 = arrayIntegers.slice(4);       // [5]
let arrayIntegers4 = arrayIntegers.slice(-3, -1);  // [3, 4]

Note: The slice() method does not mutate (change) the original array; instead, it returns a new array containing the extracted elements.
