Unit 3 Summary
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
, andelse
. - 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.
