There are three main types of operators:
Arithmetic operators such as add (+), subtract (-), times (*), divide (/) and other numerical calculations.
Comparison operators, which give the result of a comparison between numbers or strings, for example greater than (>), less than (<), equal to (==).
Logical operators include things like AND (&&) and OR (||).
There are other operators, such as assignment and concatenation.
