Booleans

JavaScript booleans represent either true or false values. We use Boolean() function to determine whether an expression is true or not. To compare conditions you can use equal to (==), greater than (>) and less than (<) symbols. This operators can be used to determine equality or difference between variables and values. You may also use (!=) to determine that the two expressions are not equal to each other. You could also use operators to assign a value to a variable based on some condition. So for example you want to come back with a certain statement based on the users condition, you can use the following line

     variablename = (condition) ? value1:value2

 in which case value one would return "You are old enough" and value two would return "You are old enough".
