Explanation:

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.
