How to Create a JavaScript Function with More than Two Parameters?

To create a JavaScript function with more than two parameters, you simply need to add additional parameter names separated by commas within the parentheses of the function definition. Here’s an example of a function that takes three parameters:

function multiply(a, b, c) {
  return a * b * c;
}

You can call this function and pass in three arguments, like this:

let result = multiply(2, 3, 4);
console.log(result); // outputs 24

Note that the number of arguments you pass in when calling the function must match the number of parameters defined in the function. If you pass in too few or too many arguments, JavaScript will raise an error.
