Why is "undefined" in the output?

Question

I am trying to print a statement using a function that contains a property of the object. The output is there but it's followed by an undefined in the next line each time i execute the function.

Answer 1

this is cuz u wrote console.log(obj1.proud()) and you are already console.logging inside the function so its like console.log(console.log("something")) so its returning undefined. Two ways to solve it:

1. use a return statement at the end of function:
return this.name instead of console.log(this.name)

2. Don't do the above method and just remove console.log() where u call the function, just call it directly. 1st ones better coz u can store its output inside variables too, coz its returning something.

Answer 2

Thank you very much 😄😄
