TypeScript 2.0 adds major updates to Microsoft’s type version of JavaScript and will make the developer work easier. When Microsoft released TypeScript 1.0 four years ago, the language proved the potential of JavaScript when combined with static types. Developers no longer had to waste time hunting bugs thanks to its compile-time error checking. TypeScript 1.1 boosted performance by up to four times because the compiler was completely rewritten, supporting more flexibility and faster iteration. Later, version 1.4 came with support for ES2015/ES6 and version 1.5 introduced support for modules and decorators. This allowed Angular 2 to adopt TypeScript, becoming Microsoft’s partner and helping the company improve this language. Finally, TypeScript 1.6-1.8 added new type system improvements and provided support for major JavaScript libraries. TypeScript 2.0 brings the following new features:
Non-nullable Types Control Flow Analysis for Types Easier Module Declarations Read-only properties Improved typings acquisition
The TypeScript team has promised it will continue to work with its partners and the community to improve TypeScript’s type system to “allow users to further express JavaScript in a statically typed fashion. In addition, we will focus on enhancing the TypeScript language service and set of tooling features so that developer tools become smarter and further boost developer productivity.” RELATED STORIES TO CHECK OUT:
