Could you rewrite the code so that it works for any number of ingredients?

Could you check if contains(['a', 'b', 'c'], "0") return the value you expect?

Does the following function call returns the value you expect?
tally(["toString", "toString"]);
Suggestion:
- Look up an approach to create an empty object with no inherited properties, or
- use
Object.hasOwn()
