Static typing

One of the best features of TypeScript is its powerful type system added on top of JavaScript. This alone should appeal to any developer who is used to working with strongly typed languages, and thus, used to benefiting from great IDE support.

When you develop using C# or Java with a solid editor/IDE, you get powerful auto-completion, refactoring support, access to the documentation, in-context hints, and warnings and errors, all for free. TypeScript provides the same developer experience for the JavaScript ecosystem and allows developers to benefit from a highly productive development environment. This is great for all developers, not only larger teams.

Whether you're a fan of static or dynamic typing, TypeScript will make you happy as types in TypeScript are optional and TypeScript has very powerful type inference capabilities. Moreover, type inference improves with each new release of the compiler.

Put simply TypeScript definitely will help you discover bugs earlier and it will help you to better organize and structure your code, whether you're working on a small application or a large project.
