This lesson discusses branching using constructions if, else if, and else in Rust. Interestingly, in Rust 'if' is an expression that yields value, so it can be used directly to set the value of a variable. This ability makes conditional codes more concise and declarative.

Conditional statements using 'if', 'else if', and 'else'
The condition does not require a regular parenthesis around it
Since 'if' is an expression, the result can be directly stored in the variable.
Each branch on the expression if must return a consistent data type
