In JavaScript, functions are a fundamental building block of programming. They allow us to encapsulate code for reuse and organization. One powerful feature of functions in JavaScript is the ability to work with variable numbers of arguments using rest parameters.
If you’ve ever wondered how to handle an unknown number of arguments in your functions, rest parameters are the solution you’ve been looking for.
What are Rest Parameters?
Rest parameters were introduced in ECMAScript 6 (ES6) and provide a convenient way to work with an indefinite number of arguments as an array within a function. This means you can pass any number of arguments to a function, and they will be bundled into a single array parameter. This simplifies the handling of multiple arguments and makes your code more flexible and concise.
How to Use Rest Parameters
To define a rest parameter, you simply prefix the last parameter of a function with three dots (...). This tells JavaScript to gather any remaining arguments into an array. Let's…
