Tests:
Splice
const a = ["a", "b", "c", "d", "e"]; const indexToRemove = 2; const b = a.splice(indexToRemove, 1);
Slice using spread uperator
const a = ["a", "b", "c", "d", "e"]; const indexToRemove = 2; const b = [...a.slice(0, indexToRemove), ...a.slice(indexToRemove + 1)];
Slice using concat
const a = ["a", "b", "c", "d", "e"]; const indexToRemove = 2; const b = a.slice(0, indexToRemove).concat(a.slice(indexToRemove + 1));
Filter
const a = ["a", "b", "c", "d", "e"]; const indexToRemove = 2; const b = a.filter((_, i) => i !== indexToRemove)
