-        Expression expansion lets you write a single expression that can expand to multiple different expressions. So rather than repeatedly defining separate expressions, you can avoid redundancy while adhering to clean code principles (Do not Repeat Yourself - DRY). Since expressions are reusable, they aid in writing concise code.
