static-methods

I want to write es6 class: class SomeClass { static prop = 123 method() { } } How to get access to static prop from method() without use SomeClass explicitly? In es6 it can be done with this.constructor , but in typescript this.constructor.prop causes error " TS2339: Property 'prop' does not exist on type 'Function' ". but in typescript this.constructor.prop causes error "TS2339: Property 'prop' does not exist on type 'Function'". Typescript does not infer the type of constructor to be anything beyond Function (after all ... the constructor might be a sub class). So use an assertion: class

While I understand the $this variable is not available when a method is called in a static context, to assist in decoupling my application components from one-another I figured it would make sense to call static methods from an instance. For example: class MyExample{ private static $_data = array(); public static function setData($key, $value){ self::$_data[$key] = $value; } // other non-static methods, using self::$_data } // to decouple, another class or something has been passed an instance of MyExample // rather than calling MyExample::setData() explicitly // however, this data is now

I am currently building an API which will be used by a webservice. I was wondering what performance issues I could meet if I built my API using a large amount of static methods . The original idea was to build expert objects which act as services. In a single user environment this approach was great! But I will soon need to port this to a multi/concurrent user environment. What kind of performance issues might i encounter with this kind of architecture? Best regards, Edit: The static methods hold no static variables and have no side effects. They simply execute a normal routine where

I am making a database to store information about the users of my website (I am using stuts2 and hence Java EE technology). For the database I'll be making a DBManager. Should I apply singleton pattern here or rather make all it's methods static? I will be using this DBManager for basic things like adding, deleting and updating User profiles. Along with it, I'll use for all other querying purposes, for instance to find out whether a username already exists and to get all users for administrative purposes and stuff like that. My questions What is the benefit of singleton pattern? Which thing is
