Typescript Mini Reference A Quick Guide to the Typescript Programming Language for Busy Coders

Typescript is a better jаvascript, It is a statically typed, safe programming language, which uses more or less the same syntax as jаvascript. Typescript programs are compiled to jаvascript, and they can be run anywhere jаvascript is supported. It is widely used by professional jаvascript developers, for frontend development (e.g., Angular, React, and VueJS) as well as for backend development (e.g., Node.Js and Deno).
This book is a "mini" language reference on the Typescript programming language. We go through all essential features of Typescript (as of versions 4.8 and 4.9), and some new ECMAScript features, in this book.
Although it is written as a reference, however, you can read it more or less from beginning to end and you should be able to get the overall picture of the Typescript language if you have some prior experience with programming in Typescript or modern jаvascript (ES2015 and later).
