TypeScript Online Compiler

TypeScript is basically a syntactical superset of JavaScript that helps tighten integration with the editor. This open-source and object-oriented language was launched in 2012. Being a strongly typed programming language, it facilitates easy variable and function parameter control. Its objective is to enable IDEs to offer a richer environment for real-time error location and resolution.

If you have a large JavaScript project in hand, adopting TypeScript will help you develop a more robust application that is deployable like regular JavaScript software. TypeScript makes JavaScript code simpler so that the developers can easily read and debug it. The language also offers highly productive development tools for different JavaScript IDEs and practices.

TypeScript is usually used when there is a large codebase involved, and multiple programmers are working on a project. It also works as a great alternative to JavaScript when the developers are accustomed to strongly-types programming languages like C# and Java. Also, when you use a library or framework like Angular 2 that recommends TypeScript, you should opt for it.

Top companies that use TypeScript include Microsoft, Asana, Medium, Typeform, Lyft, Canva, BlaBlaCar, and Slack.
