TypeScript High Performance

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>

Static code analysis with TSLint


In the preceding section, we explored how unit testing can be leveraged as a means to achieve code correctness. This involved compiling our TypeScript and executing it against a test framework to find hidden bugs in our implementation.

What if there was a way to do some sort of sanity check on our code even before executing it, even before compiling it? Well great news, there certainly is a way to achieve this, and most real-world projects have this sanity check performed as a part of their development process. Let's explore what this actually means.

Formally, this sanity check is known as Static Code Analysis, which essentially means performing analysis on the code statically without executing the code. This process analyzes the code syntax, its structure, and helps to ensure that it adheres to some benchmark standards we established.

This process ensures code readability and thereby maintainability. As you have learned, it makes the code easier for a newer...
