Basic JavaScript - Using Objects for Lookups

Please Tell us what’s happening in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!

TypeError : lookup is not a function

Yes, lookup is not a function. It is an object, so you cannot use () and call it like a function.

Can you say more?

() calls function calls array right

You don’t really “call” an array or an object. You “access” an array or object member.
