The built-in collections package provides several specialized, flexible collection types that are both high-performance and provide alternatives to the general collection types of dict, list, tuple and set. The module also defines abstract base classes describing different types of collection functi...

While everything in Node.js is generally done asynchronously, require() is not one of those things. Since modules in practice only need to be loaded once, it is a blocking operation and should be used properly. Modules are cached after the first time they are loaded. Should you be editing a modul...

In the basic case, a model is Python class that maps to a single database table. The attributes of the class map to columns in the table and an instance of the class represents a row in database table. The models inherit from django.db.models.Model which provides a rich API for adding and filtering ...

The basic pattern for writing a module is to fill a table with keys that are function names and values that are the functions themselves. The module then returns this function for calling code to require and use. (Functions are first-class values in Lua, so storing a function in a table is easy an...
