And yet, JS and TS – key differences
For its part, TypeScript has a static typing. TypeScript type system offers you incredibly rich opportunities: interfaces, enums, hybrid types, generics, union/intersection types, access modifiers, and much more. And you are not allowed to use undeclared variables.
The advanced static type system of TypeScript helps to avoid such a situation, but cost you more time to set up a codebase with proper strict typing. However, one of the goals for the development of TypeScript was to help catch mistakes early and make development efficient.
Server-side / client-side
Let’s get on with it.
To learn more, you can clone the “DefinitelyTyped” repository from GitHub to get access to all popular libraries. When you need to use external script files in TS, you understand how convenient declaration files are.
Another feature that declaration files offer and that can be helpful is completion in your editor. That speeds up your development process and makes coding easier.
Size of projects
TypeScript is a language that makes the code more consistent, clean, simple, and reusable. Thanks to static typing and declaration files TypeScript code is much easier to maintain and share. Also, TypeScript works great in bug prevention and helps to avoid spending time looking through code to find a silly mistake. So, it is better to use TypeScript for large projects.
Should you use TypeScript in all projects? No.
