Last year I wrote about having heredoc like strings available in JavaScript. Today I figured i’d briefly bring the topic back, providing a solution for returning an array of all comments found in a function:
Why is this useful? As you may know, writing multiline strings in JavaScript isn’t always the prettiest especially when you have to use \n or \r\n. On the other hand, let’s imagine that we have some multiline strings stored inside of a function as comments:
As you can see in the above jPaq Proof, by using the getComments function on a function which contains comments you can pull the comments out as if they were HEREDOC strings. Have fun! 😎
NOTE: It is important to remember that if you are minifying your code, these comments will most-likely be stripped out. In this case you will want to find a different solution such as using the string escape characters (\r\n or \n).
