The Quiz question is holding a wrong answer.

In question 'Which of the following functions correctly implements default parameters?', I think the answer is obviously "function myFunction(name = 'Ken')". But I'd tried for several times, it always said I was wrong. Could you please check the setting of the Quiz?

Thank you for point this out! The correct answer (per the quiz) is using invalid syntax. We'll get it fixed.

The correct syntax should be:

function myFunction(name = 'Ken') { … }

Well, I made a mistake, the answer is "function myFunction(let name = 'Ken') { … } ", Another question is, when I add it to my project , the error comes like

function myFunc(let name = 'Tiger'){
