Will TypeScript Wipe Out JavaScript?

TypeScript has become a popular choice for web development, offering a faster and simpler alternative to JavaScript since its release 12 years ago.

Developed by Microsoft, TypeScript is used in the creation of products like Visual Studio Code and Office 365. Google’s Angular framework, based on TypeScript, is utilized by platforms like YouTube and Google Cloud.

Amazon also uses TypeScript for its AWS Construct Library packages, providing mappings to various programming languages.

GitHub’s recent innovation graph shows TypeScript climbing from the 11th to the 4th most used language on the platform in the past four years.

JavaScript developers appreciate TypeScript for its static typing, allowing for more robust and maintainable code.

With features like enums, interfaces, and type-checking, TypeScript offers a more organized coding environment and compatibility with web browsers.

Andres Hejlsberg, the chief architect at Microsoft, highlights TypeScript’s ability to support large codebases and collaborations, areas where JavaScript falls short.

A better JavaScript

TypeScript’s unique features and powerful tooling make it a preferred language for developers looking to create large-scale applications and collaborate on complex projects.

Type-inference and compatibility with existing JavaScript libraries make it easy for developers to transition to TypeScript gradually.

The partnership with Angular has also contributed to TypeScript’s growth, with frameworks like Aurelia, Ionic, and NativeScript adopting the language.

Despite its rise in popularity, JavaScript remains a widely used language, with many TypeScript developers still utilizing JavaScript in their projects.

The Future of TypeScript

As TypeScript evolves, the team focuses on improving speed and expressiveness, addressing challenges like consuming unstructured responses from large language models (LLMs).

Projects like TypeChat aim to connect natural language to programming, providing structured interactions with LLMs through TypeScript schemas.

Features like “isolated declaration emit” enhance TypeScript’s capabilities, with the team working towards a seamless development experience without the need for a build step.

With community feedback and ongoing advancements, TypeScript’s popularity continues to grow, potentially surpassing JavaScript in the future.
