What happens if you forget to close a multi-line comment in JavaScript?
A). The code within the comment will execute as normal
B). It will cause a syntax error
C). The comment will extend indefinitely
D). The code will be wrapped in a single-line comment
What is the primary advantage of using comments to prevent execution compared to deleting code temporarily?
A). Comments allow developers to execute the code by toggling a flag
B). Comments provide a way to document why the code is disabled and can be re-enabled easily
C). Comments make the code more complex and difficult to understand
D). Comments improve code execution speed
Which statement about using comments to prevent execution is accurate?
A). Comments are executed as code
B). Comments are ignored by the interpreter
C). Comments can contain executable code
D). Comments increase code performance
How can comments be used effectively to prevent execution without altering the code structure in JavaScript?
A). By using comments to add complexity to the code structure
B). By adding comments at the beginning and end of the code block
C). By wrapping the code block in multi-line comments and leaving a clear explanation
D). By replacing the code with a placeholder string
What should be avoided when using comments to prevent code execution?
A). Using comments to provide explanations about the code
B). Commenting out entire sections of code without a clear reason
C). Using comments to add debugging information
D). Using comments within functions
How can comments be leveraged during debugging to prevent the execution of specific code blocks temporarily?
A). By surrounding the code block with {}
B). By commenting out the code block using // or /* */
C). By using the preventExecution keyword
D). By replacing the code with a placeholder string
How can multi-line comments be used to disable specific code blocks in JavaScript?
A). By adding a DISABLED keyword at the beginning of the code block
B). By enclosing the code block in /* */
C). By using single-line comments // to comment out the code block
D). By adding the disable: true attribute to the code block
What should developers do before deploying code that contains disabled code segments using comments?
A). Ensure that all comments are removed
B). Ensure that comments are added for each line of disabled code
C). Ensure that the code is well-documented with comments explaining the disabled segments
D). Ensure that the code contains sufficient debugging information to enable the disabled segments
What happens if you mix single-line and multi-line comments incorrectly in JavaScript?
A). It will cause the code to execute twice
B). It will result in a syntax error
C). It will create a new comment type called hybrid comments
D). It will disable all comments in the code block
What is the purpose of using comments to prevent execution in programming?
A). To increase code execution speed
B). To improve code readability
C). To disable specific code segments temporarily
D). To add complexity to the code structure
