Unit 3: Boolean Expressions and if Statements

  • Introduces Boolean data type (true/false) and logical expressions.
  • Focuses on decision-making structures using if, else if, and else.
  • Covers relational operators (==, !=, <, >) for comparisons.
  • Uses logical operators (&&, ||, !) to build more complex conditions.
  • Explores nested if statements and the role of indentation for readability.
  • Introduces short-circuiting and why it matters in logical operations.


Connections to PBL:

  • In a front-end project, Boolean expressions are used for conditional rendering (e.g., showing a loading spinner or error message).
  • API logic relies on Boolean expressions to validate requests (e.g., checking if a user is authorized before providing access).
  • On the back-end, Boolean logic is often used to control flow, such as allowing or denying access based on user roles.
