NOTE: If necessary, you can attempt to rename a TS file to use the MPEG extension and open it as an MPEG movie.

.TS File Association 2

A TS file is a text file that contains TypeScript code, an open source programming language developed by Microsoft. TypeScript is a superset of ECMAScript 2015, which is a superset of JavaScript. It is used for developing medium- to large-scale JavaScript applications for server-side or client-side execution. TS files are similar to JavaScript .JS files.

More Information

TypeScript was made public in late 2012 and was developed for the purpose of easing the development of components in complex JavaScript code. It is a statically typed superset of JavaScript that compiles to plain JavaScript, which can be run on web browsers, in Node.js, or in any JavaScript engine supporting ECMAScript 3 or later. The language extension comes with all the features of JavaScript while adding features such as static type checking, interfaces, type erasure, enumerated type, and namespaces.
