What are the differences between lambda functions and normal functions in programming languages?

What are the differences between lambda functions and normal functions in programming languages?

Lambda functions are anonymous and often used for short, throwaway functions, while normal functions are defined with a name and can be reused.

Can you give me examples of lambda functions in Python and JavaScript?

Sure! In Python, a lambda function can be defined as lambda x: x + 1. In JavaScript, you can use an arrow function like const addOne = x => x + 1;.

Are there any performance differences between using lambda functions and normal functions?

Generally, lambda functions can be slightly faster for small tasks due to less overhead, but the difference is often negligible.

When should I use lambda functions instead of normal functions?

Use lambda functions for short, simple operations, especially when passing functions as arguments, like in map or filter.
