質問 # 68
Refer to the code:
01 console.log('Start');
02 Promise.resolve('Success').then(function(value) {
03 console.log('Success');
04 });
05 console.log('End');
What is the output after the code executes successfully?
正解：B
解説：
________________________________________
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge console.log('Start') runs immediately (synchronous).
Promise.resolve().then(...) places the callback in the microtask queue. The .then handler does not run immediately.
console.log('End') runs next (still synchronous).
After the synchronous script finishes, the microtask queue runs, logging "Success".
Execution order:
Start
End
Success
This matches option B.
________________________________________
JavaScript Knowledge Reference (text-only)
Promise .then() callbacks execute after the current call stack finishes (microtask queue).
Synchronous logs run immediately, before promise callbacks.

質問 # 70
Which three browser specific APIs are available for developers to persist data between page loads?
正解：A、B、F
解説：
A pattern for creating a new scope, not a persistence mechanism.
Variables inside an IIFE are still lost when the page reloads.
Thus, the three persistent browser APIs are:
localStorage
indexedDB
cookies
Explanation:
Comprehensive and Detailed Explanation From Exact Extract JavaScript knowledge:
We want mechanisms that persist data between page loads (i.e., after refresh or navigation), in the browser.
A . localStorage
Part of the Web Storage API.
Data persists across page reloads and browser restarts (until explicitly cleared).
Scoped per origin (protocol + host + port).
This is a correct persistent storage API.
B . indexedDB
A low-level, client-side NoSQL database in the browser.
Stores large amounts of structured data and persists across reloads and sessions.
This is also a correct persistent API.
C . cookies
Small key/value pairs stored by the browser and often sent with HTTP requests.
Can have expiration dates and persist across page loads and sessions.
They are a traditional persistence mechanism in browsers.
So cookies also qualify.
D . global variables
Global JS variables exist only for the life of the current page context.
When the page is refreshed or navigated away, they are lost.
They do not persist between page loads.
