The Section Cutter
Medium+25 XP
Mission Briefing
The Royal Chef needs exactly the first three ingredients from a massive, endless conveyor belt. You must build a mechanical blade to cut this exact section without damaging the rest!
The Concept: Slicing Arrays
The .slice(start, end) method copies a portion of an array into a brand new array.
- It does not mutate the original array.
- The item at the
endindex is not included in the copy. Example:[10, 20, 30, 40].slice(0, 2) // Returns [10, 20]
The Objective
Your function receives an array data (which will always have at least 3 items).
- Isolate and copy the first three elements into a new array.
- Return that new sliced array.
