TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It adds optional static types, classes, and interfaces to JavaScript to help catch errors. TypeScript supports standard JavaScript features like functions, arrays, objects, and standard types like string, number, boolean, and date. It also supports type annotations, classes, interfaces, enums, and generics to provide more robust code. Projects at Band use TypeScript across their mobile, portal, and system codebases to build reliable applications.
