What Is a Lambda Expression?

A lambda expression:

• Has no function name
• Contains a single expression
• Returns the result automatically

It is useful when a full function definition would be unnecessary.

Common Use Cases

• Simple transformations
• Short-lived helper functions
• Use with functions that expect callable arguments

📌 Note:
Use lambda expressions for clarity, not complexity.
