Two can play that game

Arguments (Continued)

We have seen how to add one argument to the a function, We are now going to see how to add two (or more).

Remember when arg1 was added in the parens ()?

let myFirstFunction = (arg1) => {
  console.log(arg1)
}
// Now we call the function
myFirstFunction('using my first arg') // "using my first arg"

Well now, all we need to do to add a second argument arg2 is to add a comma , after arg1 and then add arg2.

let myFirstFunction = (arg1, arg2) => {
  //<-arg1 and arg2 are inputed in between the parens
  console.log(arg1, arg2)
  //            ↖   arg1 and arg2 are "transfered" to be the args of console.log()
}
// Now we call the function
myFirstFunction('first arg', 'second arg')
// "first arg"
// "second arg"

For more args, you will need to simply repeat the same process. Example with arg3 and arg4:

let myFirstFunction = (arg1, arg2, arg3, arg4) => {
  //<as many arguments as needed
  console.log(arg1, arg2, arg3, arg4)
} //<-end of the scope of the function
// Now we call the function
myFirstFunction('first arg', 'second arg', 3, 4)
// "first arg"
// "second arg"
// 3
// 4

Finally, please note that you can name your arguments however you please. Just make sure that you reuse the proper name inside the scope of your function. Example:

let myFirstFunction = (continent, country, city, temperature) => {
  //<as many arguments as needed
  console.log(continent, country, city, temperature)
} //<-end of the scope of the function
// Now we call the function
myFirstFunction('Europe', 'France', 'Paris', '30°C')
// "Europe"
// "France"
// "Paris"
// "30°C"

Instructions

You want to conquer the world! (of entertainment).

In this exercise you will have to declare the function duos.

This function will take two arguments and will log them together with an and and a !

Example: If the arg1 is Batman and arg2 is Robin, the fonction should log : Batman and Robin!

You will then declare the function duosWork. This function will take three arguments and will log them togethers as in the example below. Example: If the arg1 is Batman, thearg2 is Robin, and the arg3 is protect Gotham. the fonction should log : Batman and Robin protect Gotham!
