Why doesn't RegExp take into account line breaks?

Question

JavaScript

I wrote a regular expression new RegExp('(<%--)(.*)(--%>)','gim') , which should find everything that is enclosed in the character sequence <%-- --%> . Within a single line, this works fine, but if there is a line break between the <%-- --%> character sequences , then everything will break. I decided to catch the line break with this regular expression: (<%--)([\s\S]*)(--%>), but it does not work correctly.
Tell me how to write a regular expression that will take into account line breaks?

Answer 1

(<%--)([\s\S]*?)(--%>)

Answer 2

Decimal point denotes any character except newline

Accordingly, the regular expression should be as follows: /(<%--)((?:.|\n)*)(--%>)/gmi.
