Lecture Description
Yo guys, today we're gonna look at boolean values (true and false values) and the different values that are seen as "truthy" or "falsey" by JavaScript. To determine whether a value is truthy or falsey, we can use the built in JavaScript Boolean() function.
Other expressions can also be evaluated as true or false, for example, is 7 greater than 5. Is X smaller than Y etc. We'll go on to use expressions like this when we start using if statements and loops.
As always, any questions - just comment below :).
