Sir, is there any difference between Promise.reject() and new Promise((_, reject)=>reject()) ? I don't see any difference in browser even when promises passed as value.


2nd question: Javascript is synchronous in definition. Since introduction of Promises from es6 version, did javascript definition changed to asynchronous?
