You can use a Template Literal function to escape the characters within the string using a Regular Expression. You can then use that string to propagate a new RegEx filled with escaped characters:

    function escape(s) {
        return s[0].replace(/[-&\/\\^$*+?.()|[\]{}]/g, '\\$&');
    };
    
    var or = escape`||`;
    var and = escape`&&`;
    console.log(new RegExp(`${and}|${or}`)); // "/\&\&|\|\|/"
