FAQs
TypeScript is an open-source programming language developed by Microsoft. It is a strict syntactical superset of JavaScript, which means it adds optional static typing to the language. This helps developers catch errors early, before the code is even run.
TypeScript’s static typing makes it ideal for large, complex applications with multiple developers. It makes the code more readable, easier to refactor, and helps prevent common bugs that are hard to find in plain JavaScript, leading to more stable and maintainable software.
Frontend Development Services is the practice of building the user interface (UI) and user experience (UX) of a web application the part the user sees and interacts with. This is most commonly done using frameworks like React, Angular, and Vue.js, all of which work best with TypeScript.
Angular is built entirely with TypeScript. React and Vue.js, while originally JavaScript-based, are now predominantly used with TypeScript in professional environments. TypeScript is also heavily used in backend development with Node.js (using frameworks like NestJS).
Hiring TypeScript Developers means you are hiring engineers who are proficient in both JavaScript and the advanced features of TypeScript. They are skilled at building modern, type-safe applications and understand how to structure code for long-term scalability.
Rates from top-tier firms in the USA typically range from $75 to $150 per hour. A full-scale, custom enterprise application can cost anywhere from $75,000 to over $500,000, depending on its complexity.
Yes. Because TypeScript is a superset of JavaScript, you can migrate an existing application incrementally. The Best TypeScript Development Companies specialize in this, allowing you to gradually add types to your codebase without a complete, high-risk rewrite.
