This is a list of calendar and scheduling tutorials written in TypeScript. TypeScript is a new programming language created by Microsoft that extends JavaScript and adds new features to it, like static typing.
Applications written in in TypeScript need to be compiled to JavaScript before they can be run in the browser. This adds a complication step to the deployment workflow (JavaScript can be run directly) which makes the deployment more complicated. However, there are tools available that automate the compilation. Also, the compiler can perform additional optimizations (like the Angular compiler does) and that can compensate for the hassle.
The most prominent use of TypeScript is probably the Angular framework which chooses TypeScript as its primary language.
DayPilot Pro for JavaScript includes TypeScript definitions that describe the DayPilot API. Some IDEs (like WebStorm or Visual Studio) can read the TypeScript definitions and offer code hints for JavaScript projects as well.
