Can anyone help me with the code function in JavaScript that takes a parameter and outputs its double. This is the code.

Question

Function double() {
Output num*2
}

Answer 1

Sure! Can you please show us your code attempt so we can check on it?

Answer 2

From your profile I can see that you did the Web Development Fundamentals courses.

Please have a look at lesson 33.1 on functions again, especially the section with the heading "Parameters". Also take a close look at the spellings of keywords, for example it is "function", not "Function".

If you need more help, you can show us your updated code here.

Answer 3

Remember that JavaScript tries to guess what data type you want to use, so if it guesses wrong then you can use what's called "implicit type coercion" to tell it use the right type.

Answer 4

Alright
Thanks a lot
