Regex to remove multi line comments

Question

I am trying to use this regex (JS):

/\\/\\*(.*)\\*\\//g

To replace

/*
sdandsads
*/

with nothing.

Answer 1

Two problems:

1. In javascript, there's no dotall modifier. You'll have to use a hack to allow matching newlines, such as using [^].
2. You're using greedy matching. If there are multiple comments in your input, everything between them will be eaten.

Solution:

/\/\*[^]*?\*\//g

Example:

> '/*abc\ncde*/qqq/*iop\n\njj*/'.replace(/\/\*[^]*?\*\//g, '')
qqq
