How can comments be used effectively to prevent execution without altering the code structure in JavaScript?

In JavaScript, what is the purpose of using multi-line comments to prevent execution?

A). To provide detailed explanations about the code

B). To execute the code block

C). To improve code performance

D). To increase code complexity

How can developers ensure that comments used for preventing execution do not affect the code's functionality?

A). By using comments only at the end of the code block

B). By ensuring that comments are well-documented and provide clear explanations

C). By using multi-line comments for single-line comments, ensuring consistency

D). By using single-line comments to disable code, ensuring that multi-line comments are used for documentation

Which type of comments is commonly used to prevent code execution temporarily?

A). Single-line comments

B). Multi-line comments

C). Inline comments

D). Block comments

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

Which of the following is a valid way to prevent the execution of code in JavaScript temporarily?

A). By adding a DEBUG keyword at the end of each line of code

B). By wrapping the code block with {}

C). By using single-line comments // to comment out the code

D). By adding the execute: false attribute to the code block

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 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

How can developers maintain code readability when using comments to prevent execution in JavaScript?

A). By using cryptic comments that only developers can understand

B). By adding extensive comments that explain every line of code

C). By using single-line comments to disable code segments and avoid multi-line comments

D). By removing all comments from the code

Which statement accurately describes the use of comments to prevent execution in JavaScript?

A). Comments are executed as code and should be avoided for preventing execution

B). Comments are used only for providing explanations and cannot prevent execution

C). Comments are ignored by the interpreter during execution, making them suitable for preventing code execution

D). Comments can be used to disable specific code blocks temporarily, aiding in debugging and development

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
