What is the difference between slice and splice

Here are the key differences between slice() and splice() methods in JavaScript arrays:

| slice() | splice() |

| ------------------------------------------------- | --------------------------------------------------- |

| Does not modify the original array (immutable) | Modifies the original array (mutable) |

| Returns a shallow copy (subset) of selected elements | Returns an array of the removed elements |

| Used to extract elements from an array | Used to add, remove, or replace elements in an array |

| Syntax: array.slice(start, end) | Syntax: array.splice(start, deleteCount, ...items) |

Summary:

- Use slice() when you want to copy or extract elements without altering the original array.

- Use splice() when you need to add, remove, or replace elements and want to change the original array.
