Classes and Objects are used to to make your code more efficient and less repetitive by grouping similar tasks. A class is used to define the actions and data structure used to build objects. The objects are then built using this predefined structure. class <ClassName> [ extends <Par...

Tables are supported only in certain flavors of Markdown, including Markdown Extra and Github Flavored Markdown, but not in the original Markdown syntax or in CommonMark. Markdown tables are also not supported on Stack Exchange sites (with the exception of the Documentation beta).

Properties: Associated with a type Variables: Not associated with a type See the Swift Programming Language iBook for more information.

Some implementations of Markdown, such as Stack Exchange's, support spoiler quotes, which look the same, but hide the content of the quote until you click on it.

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...

@interface ClassName (categoryName) // ClassName is the class to be extended // Method and property declarations @end To avoid method name clashes, it is recommended to use prefixes (like xyz_ in the example). If methods with the same name exist, it is undefined which one will...

Unit testing describes the process of testing individual units of code in isolation from the system that they are a part of. What constitutes a unit can vary from system to system, ranging from an individual method to a group of closely related classes or a module. The unit is isolated from its ...

A tuple type is a comma-separated list of types, enclosed in parentheses. This list of types also can have name of the elements and use those names to refer to the values of the individual elements. An element name consists of an identifier followed immediately by a colon (:). Common use - We ca...
