Comparing Anonymous Functions and Named Functions

What are the main differences between anonymous functions and named functions?

Anonymous functions, or lambda functions, are defined without a name, while named functions have a specific identifier. Named functions can be reused and are easier to debug, while anonymous functions are often used for short, one-time operations.

Can you give me an example of each?

Sure! A named function in JavaScript looks like this: function add(a, b) { return a + b; }. An anonymous function would be: const add = function(a, b) { return a + b; };.

When should I use anonymous functions?

Anonymous functions are great for callbacks or when you need a function for a short duration, like in array methods such as map or filter.

Are there any performance differences between the two?

Generally, there isn't a significant performance difference. However, named functions can be more efficient in terms of memory usage if reused multiple times.
