Splice and slice are methods used in programming to manipulate arrays.
Splice is used to add or remove elements from an array at a specific index.
Slice is used to extract a portion of an array and returns a new array.
Example of splice: array.splice(2, 0, 'new element') - adds 'new element' at index 2.
Example of slice: array.slice(1, 4) - extracts elements from index 1 to 3.
