SICP has been influential in computer science education, and several later books have been inspired by its style. Structure and Interpretation of Classical Mechanics (SICM), another book that uses Scheme as an instructional element, by Gerald Jay Sussman and Jack Wisdom; Software Design for Flexibility, by Chris Hanson and Gerald Jay Sussman
In object-oriented programming, a destructor (sometimes abbreviated dtor [1]) is a method which is invoked mechanically just before the memory of the object is released. [2] It can happen when its lifetime is bound to scope and the execution leaves the scope, when it is embedded in another object whose lifetime ends, or when it was allocated dynamically and is released explicitly.
Prototype also provides library functions to support classes and class-based objects. [2] In JavaScript, object creation is prototype-based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function. The Prototype framework ...
Leaflet supports Web Map Service (WMS) layers, GeoJSON layers, Vector layers and Tile layers natively. Many other types of layers are supported via plugins.. Like other web map libraries, the basic display model implemented by Leaflet is one basemap, plus zero or more translucent overlays, with zero or more vector objects displayed on top.
This version introduces the Object.groupBy and Map.groupBy static methods, Promise.withResolvers, and the /v unicode flag for regular expressions. The Object.groupBy and Map.groupBy methods groups an iterable using the return value of a provided callback function.
OpenLayers is a JavaScript library for displaying map data in web browsers as slippy maps. It provides an API for building rich web-based geographic applications similar to Google Maps and Bing Maps. It is open-source, provided under the 2-clause BSD License. [2]
