Operators are used to compare and evaluate variables and expressions in our code. Operators play a very important part in programming. Without them not much would get done automatically. In the following example we use the ( == ) operator to check if a variable is equal to our literal value.


Some operators take precedence over others even if the other is the first expression, demonstrated here.
