JavaScript vs TypeScript

JavaScript

JavaScript is a dynamic, high-level scripting language primarily used for web development. It is interpreted and loosely typed, making it flexible but also prone to runtime errors.

Pros:

• Widely supported in all browsers
• Simple syntax and easy to learn
• Large ecosystem and community support
• No compilation required

Cons:

• No static type checking
• Prone to runtime errors
• Hard to manage large-scale applications

TypeScript

TypeScript is a superset of JavaScript that adds static typing and advanced features to enhance code quality and maintainability. It compiles to JavaScript, ensuring compatibility with existing JS environments.

Pros:

• Static typing reduces runtime errors
• Better code organization for large projects
• Supports modern JavaScript features
• Improved IDE support with autocompletion and refactoring tools

Cons:

• Requires compilation
• Learning curve for developers unfamiliar with static typing
• Not supported natively in browsers (needs transpilation to JS)

Conclusion

JavaScript is great for quick development and small projects, while TypeScript is ideal for large-scale applications requiring better maintainability and type safety.
