Why use: console.log(this.sound);?

Not sure what the purpose of adding this was.

If you delete that line from the speak() method, it does the same thing.

steven but what is the purpose of the method itself it doesn't make sense we still can use the sound in the constructor without any method

The main use of "console.log" is to track program progress during development. It's not generally used in final release code.

The "console.log" is what causes the "sound" message to appear on the console.

If the message was shown after you deleted the line, you probably forgot to save your change in the editor (with the menu or Ctrl-S shortcut) before re-running the program.

Mostafa Mekawy sound paramaters in the constructor is not directly related to the speak method... you could console.log any of the other parameters
