Salesforce JavaScript Developer Practice Exam

What is a primary benefit of using breakpoints in JavaScript debugging?

1. JavaScript will execute the code faster

2. JavaScript will pause execution to allow examination of current values

3. Errors will be automatically resolved during execution

4. Breakpoints prevent infinite loops

The correct answer is: JavaScript will pause execution to allow examination of current values

Using breakpoints in JavaScript debugging offers the invaluable ability to pause the execution of code at a specific line. This pause allows developers to examine the current state of the application, including variable values, the call stack, and the flow of execution. By inspecting these elements at a designated moment, developers can identify logical errors, understand how data is manipulated throughout different stages of execution, and gain insights into program behavior, facilitating a more effective debugging process. This capability stands out because it provides a direct and interactive method for developers to analyze complex code, pinpoint issues, and optimize performance based on real-time data, rather than relying solely on logging or other indirect methods. Understanding the flow of the application in real-time can vastly improve the debugging efficiency and effectiveness.
