AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript Booleans

The video tutorial explains how expressions or variables are evaluated as true or false in programming. It states that anything with a real value, including numbers and strings, is considered true, while anything without a real value is false. An example script with seven variables is used to demonstrate this concept. The boolean function is applied to test the truthiness of each variable, and the results are displayed using the getElementById method in a web browser. The tutorial concludes by showing that numbers and strings are true, while a variable with the value 0 is false.
