[All PL-400 Questions]

Suggested Answer:
Box 1: Yes -

Problem patterns: Web-use-async -
There are multiple ways to interact with the server or request resources. Common approaches that allow for synchronous communications include the following
(These scenarios should be avoided.):
✑ Usage of the XMLHttpRequest object passing in false for the value of the async parameter for the open function call var requestXhr = new XMLHttpRequest();
// Explicitly setting the async parameter to false or supplying a variable with a value of false will force this as a synchronous call. requestXhr.open('GET', '/test/test.txt', false);

Box 2: No -
=== - Strict Equality Comparison is already used in the code.

Box 3: No -
No debugger statement in the code, so web-remove-debug-script (avoid including debug script in non-development environments) does not apply.

should be NNN, unless you explicitly "use strict" , the code should run just fine.

only if you write 'use strict' on top of your code you will get an exception, if you don't write 'use strict' you'll only get a warning
