static generatePassword(){
const randomNumber = math.floor(math.random()*10000);
return randomNumber;
}
I made this code and instead of returning, it returns an error. Can anyone tell me what i did wrong?

Math is a special object, as in a class of its own. We generally refer to classes by their capitalized names.

Math.floor(Math.random())

“Sometimes you will want a class to have methods that aren’t available in individual instances, but that you can call directly from the class.”

Why? What is gained by not having a specific method available in instance?

static generatePassword() {
const password = Math.floor(Math.random() * 10000);
return password;
}
the above was in the HospitalEmployee class.

At the end of main.jsp, i logged console.log(HospitalEmployee.generatePassword);
but it gave me [Function: generatePassword]
instead of generating a random integer between zero and 10000.

Can someone please tell me if i logged it correctly?

Remember to invoke the function with () else you are only logging the object reference.

Hi, thanks for your reply and pointing out my error.
I changed it to the log below

console.log(HospitalEmployee.generatePassword());

and it came back as undefined though.
