Logical Operators

"=" is an assignment operator, e.g. If you run var x = 1; then x will have the value of 1.

"== or !=" is a comparison operator that checks if the value of something is equal to the value of something else. e.g. if(x == 1) will evaluate to true, and so will if(x == true) because 1 will evaluate to true and 0 will evaluate to false.

"=== or !==" is another comparison operator that checks if the value of something is equal to the value of, and is the same type as something else. e.g., if(x === 1) will evaluate to true, but if(x === true) will evaluate to false because 1 (the value of x) is an integer and true is a boolean.

"<" is smaller than

"<=" is smaller or equal

">" is bigger than

"between" is between two values

"not between" is not between two values

"is empty" is that there is no value inside this field
