What should be avoided when using comments to prevent code execution?

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

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

How can comments be used to prevent execution of code in programming languages?

A). By surrounding the code with curly braces {}

B). By prefixing the code with --

C). By enclosing the code in single quotes ''

D). By wrapping the code in comments /* */

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 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 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

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

In JavaScript, what is the syntax for a single-line comment?

A). // This is a comment

B). /* This is a comment */

C). # This is a comment

D).

How can a developer disable a block of code using multi-line comments in JavaScript?

A). By adding a semicolon ; at the end of each line of code

B). By using the disable keyword

C). By wrapping the code block in /* */

D). By using the disableCode function
