What is the array slice method in JavaScript?

What is the array slice method in JavaScript?

The array slice method in JavaScript is used to create a new array by extracting a portion of an existing array without modifying the original array.

How do I use the slice method? Can you give me an example?

Sure! You can use it like this: let newArray = oldArray.slice(startIndex, endIndex);. For example, let fruits = ['apple', 'banana', 'cherry']; let slicedFruits = fruits.slice(1, 3); will give you ['banana', 'cherry'].

What happens if I don't provide the end index?

If you omit the end index, the slice method will extract elements from the start index to the end of the array. For example, fruits.slice(1) will return ['banana', 'cherry'].

Can I use negative indices with slice?

Yes! Negative indices count from the end of the array. For instance, fruits.slice(-2) will return ['banana', 'cherry'].
