TypeScript High Performance

By: Ajinkya Kher

Overview of this book

<p>In a world where a tiny decrease in frames per second impacts customer engagement greatly, writing highly scalable code is more of a necessity than a luxury. Using TypeScript you get type checking during development. This gives you the power to write optimized code quickly. This book is also a solid tool to those who’re curious to understand the impact of performance in production, and it is of the greatest aid to the proactive developers who like to be cognizant of and avoid the classic pitfalls while coding.</p> <p>The book will starts with explaining the efficient implementation of basic data Structures, data types, and flow control. You will then learn efficient use of advanced language constructs and asynchronous programming. Further, you'll learn different configurations available with TSLint to improve code quality and performance. Next, we'll introduce you to the concepts of profiling and then we deep dive into profiling JS with several tools such as firebug, chrome, fiddler. Finally, you'll learn techniques to build and deploy real world large scale TypeScript applications.</p>

Summary


In this chapter, we looked closely at how browsers work behind the scenes to render a web page. We delved into networking layers as well to understand the basic flow of network request/response. You learned about the critical rendering path and the importance of optimizing it. In the process, we uncovered the 500-milliseconds and 14-KB limit we have to ensure the delivery of critical resources to complete the initial application load. We looked at several different strategies to greatly optimize the critical rendering path. Towards the end of the chapter, we also touched upon strategies to deliver high performance with active application usage while dealing with massive amounts of bidirectional data transfers.

In the next chapter, we will look into profiling and analyzing application performance using some debugging tools.
