The multiline
accessor property of RegExp
instances returns whether or not the m
flag is used with this regular expression.
RegExp.prototype.multiline
has the value true
if the m
flag was used; otherwise, false
. The m
flag indicates that a multiline input string should be treated as multiple lines. For example, if m
is used, ^
and $
change from matching at only the start or end of the entire string to the start or end of any line within the string.
The set accessor of multiline
is undefined
. You cannot change this property directly.
const regex = /foo/m; console.log(regex.multiline); // true
