What is the best practice for testing code to pinpoint a logic error within a script?
What is the best practice for testing code to pinpoint a logic error within a script?
A . Test the code in the W3C code validator.
B. Conduct a manual, line-by-line, code review.
C. Check for console errors when loading the page.
D. Insert watchpoints and comment out code blocks.
Answer: D
Explanation:
Commenting out blocks of code, also referred to as isolation testing, is another common debugging practice. If a block of code is suspected to be causing an issue, it can be temporarily commented out to see if the issue persists. If the issue is resolved when the code is commented out, that suggests that the issue lies somewhere within that block of code.
It’s important to note that manual line-by-line code review (Option B) can also be very useful, especially for catching logic errors that automated tools might miss. However, it’s more time-consuming and potentially less precise than systematic debugging with watchpoints and isolation testing, so for the purposes of this question, D is the best answer.

Which of the following is true based on the above code?
Consider the following code:
<img onmousout=” sofaPic (this) “ src=”sofa.jpg” alt=”sofa”>
Which of the following is true based on the above code?
A . The function sofaPic will be called upon when sofaPic image loads
B. The function sofaPic is called when the image fails to load
C. The function sofaPic is called when the mouse pointer moves off the image
D. The function sofaPic is called when the mouse pointer moves over the image
Answer: C
Explanation:
This is because the "onmouseout" event is triggered when the mouse pointer moves out of the element. In this case, the function "sofaPic" is called when this event occurs. Please note, however, that there is a small typographical error in your code. The correct attribute should be spelled as "onmouseout", not "onmousout".
This is how the corrected code should look:
