Evaluating Infix Expressions
This one is fairly simple, as we can use the underlying methods of the language we are writing monkey in, in this case Golang.
There are two sets of infix operators:
- Arithmatic Operators
These are +, -, /, *. This implies that the reuturned object type should
be an integer.
- Boolean Operators
These are >, <, !=, ==. The returned object type should be of type boolean.
Both 1 & 2 deal with integer operands. That meant having to support != & == for
boolean operands. Which is fairly straight forward as interfaces can be compared to
each other in Go.
That completes evaluating expressions in monkey. The next step is Conditionals! :)
