JavaScript vs TypeScript:

✨ Introduction

JavaScript is a dynamic, loosely typed language widely used for web development. TypeScript, on the other hand, is a strongly typed superset of JavaScript that provides static typing and other powerful features.

" 🎯 TypeScript is JavaScript with syntax for types." – Microsoft

key differences

Feature	🟡JavaScript	🔵Typescript
📌Type System	Dynamically typed	Statically typed
⚡Compilation	Runs directly in browsers	Needs to be compiled to JavaScript
🐞Error Detection	Detected at runtime	Detected at compile-time
🛠Tooling & Debugging	Limited static analysis	Better IntelliSense & error detection
🎓Learning Curve	Easier for beginners	Requires learning types & compilation
📈Code Scalability	Less maintainable for large projects	Better for large-scale applications

🚀Why Choose TypeScript Over JavaScript?

1. Improved Code Quality

   • Detects errors before execution
   • Reduces debugging time
   • Better Developer Experience

2. Offers IntelliSense for better code suggestions

   • Provides better code documentation with types
   • Enhanced Maintainability

3. Code is more structured and readable

   • Helps in large-scale applications with multiple developers
   • Static Typing Benefits

📝JavaScript Example

 var name = "Renuka"; // Can store any value
console.log(name);  // Output: Renuka

name = 25; // No error, but may cause issues later
console.log(name);  // Output: 25

TypeScript Example

var name: string = "Renuka"; // Explicitly defined as a string
console.log(name); // Output: Renuka

// name = 25; // ❌ Error: Type 'number' is not assignable to type 'string'
