  • Automatic Code Splitting: With Next.js, code splitting is a built-in feature. This allows the application to load only the necessary JavaScript chunks, reducing initial loading times and enhancing user experience.
  • API Routes: Next.js simplifies the creation of API routes, allowing developers to build backend functionality as serverless functions, seamlessly integrating with the frontend.
  • Static Site Generation (SSG): Next.js supports static site generation, enabling the pre-rendering of pages at build time. This leads to quicker loading times and enhanced SEO performance.

What is TypeScript?

TypeScript is a statically typed superset of JavaScript that enhances the language with static typing capabilities. Developed and maintained by Microsoft, TypeScript allows developers to catch errors during development, write more maintainable code, and enjoy enhanced tooling support.

Key Features of TypeScript:

  • Static Typing: The primary feature of TypeScript is static typing, allowing developers to define types for variables, function parameters, and return values. This helps catch type-related errors during development.
  • Enhanced Code Readability: TypeScript enhances the clarity and maintainability of code by explicitly defining types, facilitating a more comprehensible codebase structure. This approach aids developers in better understanding the intricacies of the code, ultimately contributing to improved readability and ease of maintenance.
  • Tooling Support: TypeScript is well-supported by modern IDEs, providing features like intelligent code completion, type checking, and refactoring tools, contributing to an improved development experience.
  • Compatibility with JavaScript: TypeScript is a superset of JavaScript, meaning existing JavaScript code can seamlessly integrate into TypeScript projects. This makes it easy for developers to adopt TypeScript gradually.
