TypeScript is an open-source programming language advanced and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and provides non-compulsory static typing to the language. In this typescript academic for novices, we go over the fundamental principles like variable declarations, variable types, features, interfaces, lessons and get admission to TypeScript Tutorial
Here i will explain what is Typescript
With complete tutorial.
TypeScript lets you write JavaScript the way you really want to. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. TypeScript is pure object oriented with classes, interfaces and statically typed like C# or Java. The popular JavaScript framework Angular 2.0 is written in TypeScript. Mastering TypeScript can help programmers to write object-oriented programs and have them compiled to JavaScript, both on server side and client side.

By definition, “TypeScript is JavaScript for application-scale development.”

TypeScript is a strongly typed, object oriented, compiled language. It was designed by Anders Hejlsberg (designer of C#) at Microsoft. TypeScript is both a language and a set of tools. TypeScript is a typed superset of JavaScript compiled to JavaScript. In other words, TypeScript is JavaScript plus some additional features.

TypeScript 3.5
Speed improvements #
TypeScript 3.5 introduces several optimizations around type-checking and incremental builds.

Type-checking speed-ups #
TypeScript 3.5 contains certain optimizations over TypeScript 3.4 for type-checking more efficiently. These improvements are significantly more pronounced in editor scenarios where type-checking drives operations like code completion lists.

--incremental improvements #
TypeScript 3.5 improves on 3.4’s --incremental build mode, by saving information about how the state of the world was calculated - compiler settings, why files were looked up, where files were found, etc. In scenarios involving hundreds of projects using TypeScript’s project references in --build mode, we’ve found that the amount of time rebuilding can be reduced by as much as 68% compared to TypeScript 3.4!
