and I saw the line: " If value is not a thenable, a fulfilled Promise is returned with value as its fulfillment value".

My question is what is a thenable value. For example, I saw the following code:

Promise.resolve("http://xxxx...")

The value in this case is a string of HTTP address. What is a thenable HTTP address?

I'm not asking what is the difference between a promise and a thenable object. My question is how can I know of a string is thenable or not.

That string, for example, is not a thenable. – Bergi Jul 24 '16 at 12:49
What strings are thenable, if any? – CrazySynthax Jul 24 '16 at 13:11

None actually. A primitive value can never be a thenable object. – Bergi Jul 24 '16 at 13:13
