JavaScript is the de facto programming language for developing browser-based web applications that provide the rich functionality traditionally associate with desktop applications (commonly referred to as Web 2.0 applications).
|
This class explains the JavaScript language in terms familiar to a Java Technology Developer, or a developer familiar with other object-oriented langugages, such as C++. Additionally, you will learn tips and tricks for developing web applications that leverage best practices for using client-side JavaScript, and especially the Ajax technique, to provide a richer and more responsive user experience than can be achieved by server-side logic alone.
Objective:
* List significant differences between the syntax and semantics of the JavaScript language and Java language
* Avoid bugs cause by ignorance of the differences between objects in the prototype-based JavaScript language and the class-based Java language
* Use Object Literals to bring best practice techniques of Object-Oriented Programming to your JavaScript code
* Use constructor functions, instead of class files, dynamically change the behavior or structure of any object in your JavaScript program
* Leverage prototypal inheritance to mutate objects, including the standard built-in objects, even after they have been instantiated
* Increase the performance and efficiency of your JavaScript code
* Recognize a closure in JavaScript code and explain when it is advantageous when to use a closure

Sun Microsystems
Sun ble grunnlagt med én eneste visjon som drivkraft. En visjon om datamaskiner som kommuniserte med hverandre uansett hvem som hadde laget dem. En visjon om teknikk som arbeider for deg, ikke motarbeider deg. Mens andre utviklet varemerkebeskyttede og proprietære løsninger, fokuserte vi på å hjelpe bedrifter inn i nettverksæraen. Som et resultat av dette er vi blitt dotten i .com. Vi leverer systemer og programvare som oppfyller kravene til skalerbarhet og påliteligheten som er nødvendig for å drive den elektroniske markedsplassen.
