In JavaScript, parameters are variables listed as part of a function's definition. For example, in the function function add(a, b), a and b are parameters.

What about default parameters?

MagicBuddy
MagicBuddy

Great question! You can set default values for parameters like this: function multiply(a, b = 1) { return a * b; }. If b is not provided, it defaults to 1.

Rest parameters allow you to represent an indefinite number of arguments as an array. For example: function sum(...numbers) { return numbers.reduce((acc, num) => acc + num, 0); }.
