Advantages: Encapsulation, improve code readability. Reusability to avoid code duplication. Code organization breaks the program into manageable units. Concurrency, supporting the execution of multiple tasks simultaneously. Type checking to ensure code robustness. Disadvantages: Performance overhead, extra overhead when calling functions. Debuggability, tracing function calls can be difficult. Variable scope, variables within a function are only visible within the function, which brings challenges to large programs.
