Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser . Node.js lets developers use JavaScript to write command line tools and for server-side scripting.
Node (computer science) A node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers . In graph theory, the image provides a simplified view of a network, where each of the numbers represents a different node.
Node (networking) In telecommunications networks, a node ( Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [ 1] In data ...
A node is a point along a standing wave where the wave has minimum amplitude. For instance, in a vibrating guitar string, the ends of the string are nodes. By changing the position of the end node through frets , the guitarist changes the effective length of the vibrating string and thereby the note played.
Node (networking), a point of connection in a communication network. An entity in a mesh network. Node (circuits), a region in an electrical circuit where there is no change in potential. Node (computer science), a basic unit used to build data structures. Goal node (computer science), a node in a graph that meets defined criteria for success ...
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, [ 1] except for the root node, which has no parent (i.e., the root node ...
JavaScript at Wikibooks. JavaScript ( / ˈdʒɑːvəskrɪpt / ), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior.
