Obviously you are doing basic homework ... and honestly you are not doing well

You should learn about:
- Meaning of the "var" keyword
- Correct usage of {} brackets

Hint: You don't need var ... the parameters have been automatically defined as arguments of the function. You don't need additional brackets inside the function as you don't need to have blocks there.

sir,how to make a code for this question?

Question:
Create a function that can take any number of parameters and returns a String that is a comma separated list.
e.g. myFunction(“car”, “bus”, “airplane”); // returns “car, bus, airplane”

As a general rule, the people helping out in this forum don't write code for others (especially code that appears to be for homework), but try to help with fixing code that doesn't work. You may perhaps get someone to write this script for you, but you'll be far more likely to get help if you have made a substantial effort and written some code yourself. Then someone here will almost certainly help you correct/improve your work.

e.g. myFunction(“car”, “bus”, “airplane”); // returns “car, bus, airplane”

Note that you must use normal quotation marks " and not literary quotation marks “ ” . Do not use MS WORD or other word processor to write your code. Use only a text editor.
