Each lesson is designed to provide actionable insights into speeding up your AngularJS apps.
Who is the target audience for this course?
This course is ideal for developers who are building applications with AngularJS and want to make them load and run faster. It's particularly useful for those who are interested in understanding the internal workings of AngularJS to optimize performance.
How does this course compare in scope to other AngularJS courses?
Unlike introductory AngularJS courses, this course dives deeply into performance-specific topics. It covers advanced concepts such as the $digest cycle, watcher management, and efficient handling of ng-repeat, providing specialized knowledge that complements broader AngularJS courses.
What specific tools or techniques will I learn about in this course?
The course covers several tools and techniques, including managing the $digest cycle, using $applyAsync and $evalAsync, batching renders, and using track-by expressions to minimize repaints. These techniques are crucial for optimizing the performance of AngularJS applications.
What topics are not covered in this course?
The course does not cover general AngularJS application development or basic framework features. It specifically focuses on performance optimization techniques and assumes you already have a basic understanding of AngularJS development.
How much time should I expect to commit to complete this course?
The course consists of 16 lessons, but the total runtime is not specified. Since it focuses on performance optimization, you should allocate additional time for experimenting with the code examples and applying the techniques to your projects, which can help reinforce the concepts taught.
