What is the difference between array slicing and array indexing?

What is the difference between array slicing and array indexing?

Array indexing refers to accessing a single element of an array using its index, while array slicing allows you to access a range of elements.

Can you give me an example of array indexing?

Sure! If you have an array like arr = [10, 20, 30, 40], arr[1] will give you 20.

And how does array slicing work?

Array slicing lets you get a subset of the array. For example, arr[1:3] will return [20, 30].

Are there any differences in performance between the two?

Generally, indexing is faster since it retrieves a single element, while slicing creates a new array, which can be slower.
