This Advanced JavaScript: Using Ext JS 5 training class provides instruction and practical exercises using the Ext JS 5 JavaScript Library. It examines Ext JS 5 features such as the MVVM architecture, data binding, and migrating to the latest version. This course examines core library features including the use of the Ext Element object, event handling capabilities, and working with arrays, strings, and other data types. The course provides insight on using Ajax techniques such as JSON-P and CORS. It explores various layouts and containers and examines the data-driven TreePanels, ComboBoxes, and Charts. The course explores numerous techniques for working with the GridPanel, TabPanel, and the data access classes. An in-depth treatment of creating custom components is accompanied by hands-on exercises. Finally, discussions on the build and deployment features including the creation of SASS-based CSS themes it provided.

This course introduces modern practices of JavaScript, such as OOJS and the use of design patterns. Best practices are emphasized with the use of the Ext JS library. Participants are responsible for being familiar with JavaScript concepts before taking this course.
