JavaScript Language for Java Developers - Online Course  (D63398GC10)

Format: Self-Paced Online
Other Formats:
 
 

The JavaScript language might be the most widely used programming language in the world and is the standard programming language for developing browser-based web applications. Any end-user platform that provides a standard web-browser is potentially a platform upon which a JavaScript language-based application can run. There are many server-side programming technologies, but they exist to serve the JavaScript language as the runtime logic to be run on the client-side. Modern JavaScript programs developed for a web browser platform (commonly referred to as Web 2.0 applications) can be used to provide rich functionality that has traditionally been associated with desktop applications. This class explains the JavaScript language in terms familiar to a Java technology developer, or a developer familiar with other object-oriented languages, such as C++.

This course includes a downloadable Student Workbook and associated lab files.

Students that can benefit from this course include:
* Java developers who create web applications and web application developers familiar with other object-oriented

  • Use constructor functions, instead of class files, to 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 you should use a closure
