Remove dot . sign from the end of the string

I have this requirement where it is required to remove only the last . dot sign from a string.

Say if we have var str = 'abcd dhfjd.fhfjd.'; i need remove the final dot sign which would output abcd dhfjd.fhfjd .

I found this link ( Javascript function to remove leading dot ) which removes the first dot sign but I am new to this whole thing and could not find any source on how to remove a specific last character if exists.

Thank you :)

Single dot:

if (str[str.length-1] === .)

    str = str.slice(0,-1);

Multiple dots:

while (str[str.length-1] === .)

    str = str.slice(0,-1);

Single dot, regex:

str = str.replace(/.$/, );

Multiple dots, regex:

str = str.replace(/.+$/, );
