Which three techniques can a developer use to debug the JavaScript?
Choose 3 answers
Correct Answer: A,B,C
When debugging JavaScript in a Lightning Component, developers can utilize the following techniques:
A: Use console.log() messages in the JavaScript: This is a standard debugging technique to log information to the browser console, which can help trace the execution flow or output variable values.
B: Use the browser's dev tools to debug the JavaScript: Modern browsers come equipped with developer tools that can be used to set breakpoints, step through code, and inspect variables at runtime.
C: Enable Debug Mode for Lightning components for the user: Enabling Debug Mode for users provides more detailed error messages and unminified versions of client-side libraries, making it easier to debug issues.
Using the Developer Console to view checkpoints (Option D) and debug logs (Option E) is more relevant for Apex debugging rather than JavaScript.
