In this course, the user will get an introduction on how to perform manual testing on primarily web applications. The skills aquired in this course can be used in automation testing as well.

Dive into the world of the most popular language for front-end development – JavaScript. JavaScript is a language built into almost every browser and can be used for a wide variety of tasks. Learn the basic functionality and prepare yourself for the challenges and more advanced programming techniques.

JavaScript functions from the fundamentals to modern syntax and best practices. Gain understanding of how functions shape every part of JavaScript, helping create clean, modular, and efficient code. Master both classic patterns and modern approaches to writing reusable, maintainable functions for any project.

Master the most practical and commonly used JavaScript array methods, progressing from foundational techniques to advanced functional programming patterns. Each chapter introduces a new method, explains its purpose, demonstrates real-world usage, and tests your understanding.

A practical introduction to JavaScript DOM manipulation for beginners. This course covers everything from understanding the DOM and selecting elements to modifying content, handling events, and writing efficient code. Build interactive, dynamic web pages with confidence through guided examples and hands-on practice.

Master how JavaScript represents, stores, and manipulates data through practical, real-world examples. Explore primitive and reference types, work with arrays and objects, and understand how type conversion affects program behavior. Build the confidence to handle data correctly, avoid common pitfalls, and write clean, predictable JavaScript in any project.

A practical, beginner-friendly course that teaches how to test JavaScript code. Learn why testing matters, how Jest works, and how to write reliable tests for synchronous and asynchronous logic. Move from foundational skills to advanced techniques like mocking, spying, and TDD, gaining the tools to create more stable and maintainable applications.

A clear and practical introduction to JSON and browser storage in JavaScript. Learn how to structure and manipulate JSON data, parse and stringify objects, and store information persistently using localStorage and sessionStorage.

A clear, interactive introduction to program logic in JavaScript. This course explains how decisions, conditions, and loops shape the way programs run, using relatable examples and hands-on practice. Build the foundation for writing flexible, efficient, and readable code that truly responds to logic.

Explore how modern JavaScript uses classes to organize logic, model real-world objects, and build reusable, maintainable code. Work with constructors, methods, inheritance, and encapsulation to understand how object-oriented patterns shape application structure. Apply advanced class features and build practical class designs that strengthen your ability to write clean, scalable JavaScript.

Learn how JavaScript responds to user interactions by mastering browser events, event flow, and input handling. Explore the event object, work with keyboard, mouse, and form events, and use event delegation to manage interactions efficiently. Apply these skills to build practical UI components such as tabs, dropdowns, and keyboard shortcuts, creating interfaces that feel dynamic, responsive, and intuitive.

Learn how to use proven design patterns to write cleaner, more maintainable JavaScript. Explore creational, structural, and behavioral patterns through small, practical examples that show how each pattern solves real coding challenges.

Explore the most useful web APIs. Learn to work with drag and drop, clipboard access, fullscreen mode, storage APIs, file uploads, and geolocation to create interactive and engaging web features. Reinforce your skills with hands-on mini projects that put each API into practice.

Build and manipulate objects to organize data, extend functionality with prototypes, and control context using the this keyword. Apply inheritance, composition, and immutability to write flexible, maintainable code, and use modern techniques like Object.assign and the spread syntax to create clean, efficient object patterns for any project.
