It would be nice if this was listed somewhere here for reference. It takes a lot of time to find what they mean. certainly someone has a cheat sheet

They are just javascript operators:

That’s right, as Ken explains these are standard JavaScript operators.
Thanks, As a more “visual” programmer I never even knew what to search for to get an explanation. Using the information from you link I built what I wanted which was a list of the characters offered and what they mean “generally” as I realize they are sometimes different based on the situation. Here is the cheat sheet I built for the programming challenged.
| + | Adds two numeric operands. Or performs concatenation operation when one of the operands is of string type. |
|---|---|
| - | Minus |
| * | Multiply two numeric operands. |
| / | Divide left operand by right operand. |
| % | Modulus operator. Returns remainder of two operands. |
| ++ | Increment operator. Increase operand value by one. |
| == | Compares the equality of two operands without considering type. |
| != | Compares inequality of two operands. |
| > | Checks whether left side value is greater than right side value. If yes then returns true otherwise false. |
| < | Checks whether left operand is less than right operand. If yes then returns true otherwise false. |
| >= | Checks whether left operand is greater than or equal to right operand. If yes then returns true otherwise false. |
| <= | Checks whether left operand is less than or equal to right operand. If yes then returns true otherwise false. |
| && | && is known as AND operator. It checks whether two operands are non-zero (0, false, undefined, null or “” are considered as zero), if yes then returns 1 otherwise 0. |
