Programming Topics
Master fundamental programming concepts that apply across all languages. Each topic includes interactive exercises to build real coding fluency.
Variables & Data Types
Learn how to store and manipulate data using variables. Understand different data types like strings, numbers, booleans, and more.
Functions
Master reusable blocks of code. Learn parameters, return values, arrow functions, and functional programming concepts.
Arrays & Lists
Work with collections of data. Learn array methods, iteration, manipulation, and common algorithms.
Loops & Iteration
Repeat code efficiently with for loops, while loops, and iteration methods. Control flow with break and continue.
Classes & OOP
Build with object-oriented programming. Learn classes, inheritance, encapsulation, and polymorphism.
Conditionals
Make decisions in your code with if/else statements, switch cases, and ternary operators.
Strings
Manipulate text data with string methods. Learn concatenation, template literals, and string formatting.
Objects & Dictionaries
Work with key-value pairs and complex data structures. Learn object manipulation and destructuring.
Async Programming
Handle asynchronous operations with promises, async/await, and callbacks. Build responsive applications.
Error Handling
Write robust code with try/catch blocks, custom errors, and defensive programming techniques.
Why Learn Programming Fundamentals?
Transferable Skills
Core concepts like variables, functions, and loops work the same way across most programming languages. Master them once, apply them everywhere.
Problem-Solving Foundation
Understanding fundamentals helps you think algorithmically and break down complex problems into manageable pieces.
Interview Preparation
Technical interviews focus heavily on fundamentals. Strong foundations in these topics will help you succeed in coding interviews.
Learn Faster
Once you understand core concepts, picking up new languages and frameworks becomes significantly easier and faster.
