Lifecycle React • The concepts of React: Components • The concepts of React: State • The concepts of React: Props • Handling user events in React • Lifecycle events in a React component Those topics will be the and you basically need to understand 4 concepts to get started: • Components • JSX • State • Props We'll explore all of these in this book, and we'll leave the more advanced concepts to other

State in Svelte • 4. Svelte Reactivity • 5. Svelte Props • 6. Cross-component State Management in Svelte ☐ 6.1. Passing state around using props 6.2. The context API ☐ 6.3. Using Svelte stores 6 Read-only bindings 9.6. Get a reference to the HTML element in JavaScript ☐ 9.7. Binding components props • 10. Conditional Logic in Templates • 11. Looping in Svelte Templates • 12. Promises in Svelte components the ability to change the color of the button. A better solution for this use case is to use props, which is something we'll talk about in the next chapter. But stick with me for this example
