How are multiple data values passed to a function in JavaScript?

In JavaScript, when defining a function and wanting to pass multiple data values (also known as arguments), these values must be enclosed in parentheses. This is because the parentheses are part of the syntax for function calls and signify which arguments are being passed to the function.

For example, if you have a function defined like this:

function myFunction(param1, param2) {
// function body
}

You would call this function and pass multiple values like this:

myFunction(value1, value2);

Here, value1 and value2 are the arguments being passed, and they reside within the parentheses. This demonstrates that parentheses are required for encapsulating the parameters being passed to the function.

Other options, such as using brackets or semicolons, do not adhere to the syntax for passing arguments in function calls in JavaScript. Brackets are typically used for defining arrays or accessing array elements, while semicolons are used to terminate statements. Additionally, it's not necessary for all arguments to be strings; they can be of various types, including numbers, objects, and booleans. This flexibility is a core feature of JavaScript's function argument handling.
