In a function that accepts a variable number of arguments and needs to pass them to another function, how would the rest operator be applied?
- Declare the function parameters using the rest operator, e.g., (...args)
- Use the spread operator to pass arguments to the function
- Define the function with a fixed number of parameters
- Use the arguments object within the function
The rest operator (...) is employed in function parameters to collect a variable number of arguments into an array. For example, (...args) allows the function to accept any number of arguments and access them within an array named args.
