NEW QUESTION # 72
A developer creates a simple webpage with an input filed. When a user enters text In the input field and clicks the button, the actual value of the field must be displayed in the console.
Here is the HTML file content:
The developer wrote the JavaScript code below:
When the user clicks the button, the output is always ''hello''.

NEW QUESTION # 73
After user acceptance testing, the developer is asked to change the webpage background based on the user's location. It works on the developer's computer but not on the tester's machine.
Which two actions will help determine accurate results?
Answer: C,D
Explanation:
Browsers often cache JavaScript, CSS, and HTML. This means:
* The developer may be running with the latest version (often with cache disabled in DevTools).
* The tester may still be loading an older, cached version of the page where the background-change logic does not exist.
To ensure they are actually testing the latest deployed code:
* Disabling cache (A) in the tester's browser (usually via DevTools # Network # "Disable cache") forces fresh loading of all resources on each refresh.
* Clearing cache (C) removes older resources from the browser so the next load fetches fresh files from the server.
Options B and D do not directly help verify the tester is using the latest code:
* B checks the developer's own browser, which is not the environment showing the problem.
* D suggests reworking the code before confirming whether the tester is actually loading the correct version, which is premature.
So the two actions that help produce accurate testing results are A and C.
