State Machines in JavaScript with XState, v2

• Understand the fundamentals of state machines and statecharts, and their importance in managing complex app logic.
• Learn to create state machines in pure JavaScript, and then transition to using XState for more advanced features and better scalability.
• Master the use of actions, context, guards, and various types of states (compound, parallel, final, history) within state machines.
• Explore the actor model in state machines, enabling communication between different parts of an application or even between different machines.
• Gain practical experience in testing state machines and using them for model-based testing in modern JavaScript applications.

This course, led by David Khourshid, dives deep into the use of state machines in JavaScript to create robust, predictable, and maintainable application logic. Starting with the basics, you’ll learn how to model state using pure JavaScript before moving on to XState, a powerful library that simplifies state management. The course covers key concepts like actions, context, guards, and the actor model, providing a thorough understanding of how to implement state machines in real-world applications. By the end, you’ll be able to handle complex state transitions and interactions in your JavaScript apps with confidence.

• JavaScript developers looking to enhance their skills in state management and application logic.
• Frontend developers dealing with complex user interfaces that require robust state handling.
• Engineers who want to improve their understanding of state machines and statecharts.
• Anyone interested in learning XState and applying it to large-scale JavaScript applications.

• Basic understanding of JavaScript and web development concepts.
• Familiarity with application state management principles is beneficial but not required.

• Introduction to State Machines: Learn what state machines are, how they work, and why they are beneficial for managing application state. Start by building simple state machines in vanilla JavaScript.
• Getting Started with XState: Transition from vanilla JavaScript to using XState. Learn to create, visualize, and interpret state machines with XState, and explore its powerful features.
• Actions and Context: Delve into actions and context in XState. Learn how to manage side effects and maintain extended state through context, and practice with hands-on exercises.
• Guards and Transitions: Understand guarded transitions to ensure that state changes only occur under certain conditions. Learn to model complex state behaviors using transitions, compound, and parallel states.
• Actor Model: Explore the actor model in state machines, allowing for scalable and modular application logic. Learn how to invoke actors within state machines and manage communication between different parts of the app.
• Testing and Best Practices: Learn strategies for testing state machines and how to apply model-based testing to ensure your application behaves as expected.
