Does the number of comments affect code performance?

Question

JavaScript

Perhaps a stupid question, but still - does the number of lines of comments affect the performance of the code?

Answer 1

Parsing time is affected, but the main costs are repaint and reflow . So the number of comments in HTML does not have a significant impact on performance.

Answer 2

In pure interpreters parsing strings each time, it does. In compilers and precompiler interpreters, it has no effect.

Answer 3

No.
