🌐 JavaScript Programming

A comprehensive collection of JavaScript programs demonstrating core programming concepts, including functions, arrays, objects, recursion, loops, and ES6 features.

---

📖 Description

This folder contains a variety of JavaScript programs designed to teach fundamental and advanced concepts in JavaScript. Each program is well-commented and demonstrates a specific programming concept clearly.

Programs included cover:

• Variables (var, let, const) and Data Types
• Operators and Expressions
• Functions, Arrow Functions, and Function Returning Function
• Arrays and Array Operations (Summation, Maximum, Traversal)
• Objects and Object Manipulation
• Loops (for, while) and Conditional Statements
• Recursion and Factorial/Perfect Number checks
• String Manipulation and Character Counting
• Primitive vs Reference Data Types

All programs are simple, well-structured, and perfect for building a strong foundation in JavaScript programming.
