    I can not understand why this code does not replace foo on bar

    Because the dot . explicitly does not match newline characters.

    This would work:

    "foo\r\nbar".replace(/foo[\s\S]+/m, "bar")
    

    because newline characters count as whitespace (\s).

    Note that the parentheses around foo are superfluous, grouping has no benefits here.
