// slice()

// What

// - The slice() method is used to extract a section of an array and return a new array containing the selected elements.

// - It's a non-mutating method, meaning it doesn't modify the original array.

// Why

// - Extract Subsets: You often need to work with only a portion of an array's data. slice() allows you to conveniently create a new array containing the desired elements.

// - Create Copies: Sometimes you want to work with a copy of an array without modifying the original. slice() helps create a shallow copy of the specified portion.

// - Data Manipulation: slice() can be combined with other array methods like concat() or push() to manipulate and rearrange array data.

// Syntax

// array.slice(start, end);

// - start (optional): The index at which to begin extraction (inclusive). Defaults to 0 (the beginning of the array). Negative values count from the end of the array.

// - end (optional): The index at which to end extraction (exclusive). Defaults to the end of the array. Negative values count from the end of the array.

// Example

const array = [0, 1, 2, 3, 4, 5];

const slicedArray = array.slice(1, 3); // end range will not include.

console.log(slicedArray);

console.log(array); // original array remains unchanged

// Note

// - If start is greater than or equal to end, an empty array is returned.

// - Negative values for start and end are allowed for counting from the end of the array.
