What are the Rest Parameters in JavaScript?

Rest parameters in JavaScript allow you to represent an indefinite number of arguments as an array within a function. They are denoted by three dots (...) followed by a parameter name and can be used to collect all remaining arguments passed to a function into an array. This makes it easier to work with a variable number of arguments in functions.

The rest parameter syntax allows a function to accept an indefinite number of arguments as an array, providing a way to represent variadic functions in JavaScript.
