Lazy loading (also known as asynchronous loading) is a technique used in computer programming, especially web design and web development, to defer initialization of an object until it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used.
A singleton implementation may use lazy initialization in which the instance is created when the static method is first invoked. In multithreaded programs, this can cause race conditions that result in the creation of multiple instances. The following Java 5+ example [6] is a thread-safe implementation, using lazy initialization with double ...
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed. It is a kind of lazy evaluation that refers specifically to the instantiation of objects or other resources.
Analytics tools such as Google Analytics rely heavily upon entire new pages loading in the browser, initiated by a new page load. SPAs do not work this way. SPAs do not work this way. After the first page load, all subsequent page and content changes are handled internally by the application, which should simply call a function to update the ...
The components are rendered to a root element in the DOM using the React DOM library. When rendering a component, values are passed between components through props (short for "properties"). Values internal to a component are called its state. [16] The two primary ways of declaring components in React are through function components and class ...
Hibernate can be configured to lazy load associated collections. [2]: 289–293 Lazy loading is the default as of Hibernate 3. Related objects can be configured to cascade operations from one object to the other. For example, a parent Album class object can be configured to cascade its save and delete operations to its child Track class objects.
Lazy evaluation can also lead to reduction in memory footprint, since values are created when needed. [19] In practice, lazy evaluation may cause significant performance issues compared to eager evaluation. For example, on modern computer architectures, delaying a computation and performing it later is slower than performing it immediately.
Knockout is a standalone JavaScript implementation of the Model–View–ViewModel pattern with templates. The underlying principles are therefore: a clear separation between domain data, view components and data to be displayed; the presence of a clearly defined layer of specialized code to manage the relationships between the view components
