Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Performance comparison

Now that we have built the same application using a couple of different TypeScript compatible libraries, we can compare apples with apples in terms of performance. Each framework is loading an HTML page, which will load the required libraries, along with the bootstrap.css files, and any dependent packages. Each sample application is doing exactly the same things, which include the following:

  • Loading an array of objects to use as the default collection
  • Rendering a single view for each of the objects in the collection
  • Combining each single view into a view for the entire collection
  • Rendering a title element, and a selected item element to show which item is currently selected
  • Attaching the generated HTML to the DOM

If we run each version of this application in the same browser, and open up our handy developer tools, we can start to compare how long each...
