Relative newcomer to Javascript and looking for a way to remove the last character of a string if it is a colon.

I know myString = myString.replace(\'/^\\\\:/\');<

    The regular expression literal (/.../) should not be in a string. Correcting your code for removing the colon at the beginning of the string, you get:

    myString = myString.replace(/^\:/, '');
    

    To match the colon at the end of the string, put $ after the colon instead of ^ before it:

    myString = myString.replace(/\:$/, '');
    

    You can also do it using plain string operations:

    if (myString.charAt(myString.length - 1) == ':') {
      myString = myString.substr(0, myString.length - 1);
    }
