306 PointsI haven't comprehended the Bool usage in coding. What do they do?Why do we even use true or false?
Are the Booleans an argument apart or they're used for numbers?

51,495 PointsI asked myself the same question when i started coding. I think you will understand the usage trough time. I use booleans for checking e.g. if somebody is logged in. In this case you create a variable called isLoggedin and set it to true or false. The short syntax of checking if the variable is true or false is "if isLoggedIn {}". You don't have to write "if isLoggedIn == true {}". You will come over more examples if you continue with Pasans courses.
