Which type of error are you most likely to debug using watchpoints?

When debugging JavaScript code, watchpoints are particularly useful for identifying and analyzing changes to specific variables during execution, making them most effective for addressing logic errors. A logic error arises when the code runs without any syntax or runtime errors, but it doesn't produce the expected outcome due to flaws in the logic of the code itself.

By setting watchpoints, a developer can monitor the value of variables involved in computations or conditional statements that may lead to incorrect results, allowing for better visibility into how data is manipulated at runtime. This approach enables precise tracking of variable changes, helping to pinpoint where the logical flow deviates from what was intended.

In contrast, syntax errors would prevent the code from running altogether, while runtime errors might cause the code to crash during execution, and reference errors typically occur when trying to access a variable that hasn’t been declared or is out of scope. These types of errors don't benefit as much from watchpoints since they either stop execution entirely or are reported immediately without the need for tracking changes over time.
