Description
In functional programming, we prefer immutable values over mutable values.
Mutable values (declared with var or let) can lead to unexpected behaviors and bugs. Values declared with const cannot be reassigned, which makes using them easier because you don't have to keep track of their values.
Start by creating an empty infixToFunction object using const.
