[Infographic] Typescript vs. Javascript: The Key Differences You Should Know

Typescript and Javascript are both widely known programming languages used for front-end development. If you’ve worked on any web development project, you’ve probably encountered them already. Both are scripting languages used to create interactive web pages but you might be thinking, what makes them different from each other?

What is Typescript?

Typescript is a programming language developed and maintained by Microsoft, which compiles to Javascript. It is a strict syntactical superset of Javascript and is primarily designed for the development of large applications.

Typescript is strongly-typed and follows an object-oriented structure. It supports features like classes, interfaces, namespaces, and inheritance. In short, TypeScript is basically Javascript but with extended features.

What is Javascript?

Javascript is a popular and dynamic programming language. It’s an object-based scripting language that’s light and can be used to support cross-platform development. Javascript follows the rules of client-side programming, which means it can run on the user’s web browser without the need to use resources from the webserver.

Javascript is used to add interactivity to web pages, to develop mobile applications, to create web browser-based games, and to program back-end development. Javascript can be directly added to web pages using the < script > tag and by giving them the type or attribute text/javascript. These scripts will then be executed automatically as the web page loads.

While Typescript needs to be compiled, Javascript can be executed as plain text and doesn’t need preparation or compilation.

Conclusion

Typescript and Javascript are both powerful programming languages that come with their own limits and features. Javascript is lightweight, dynamic, and flexible but the bigger the code becomes, the more complex it gets. If your team is new, small, and are working on a simple web development project, then Javascript is your best choice.

Typescript, on the other hand, is compiled to Javascript and offers more features. If you have an experienced team with great programming expertise and knowledge, Typescript is your best choice for taking on a more complex project.
