Operators
Most of the operators used in trigger scripts are similar to other programming languages; however, there are some slight differences. For example, there is a fundamental difference between the assignment operator “=“ and the comparison operator “==“. Be careful not to use “=“ to mean “equal to” in a comparison statement.

The string operator “+” is very useful for constructing error and log messages in trigger scripts.
The following tables outlines operators used in script triggers:
