Component Reusability: Create components that can be reused throughout your application. This keeps your code DRY (Don't Repeat Yourself).
Immutable State:
In React, state should be treated as if it were immutable. That means you should not modify state directly. Instead, use setState (for class components) or the useState hook (for functional components) to create a new state object.
Use PropTypes for Type Checking: PropTypes ensure that the component is used correctly by checking the types of the props being passed. This helps catch bugs early.
Keep Components Pure: A pure component’s render output is solely determined by its state and props, it doesn’t depend on browser variables or other mutable data sources.
Lifting State Up: Often, several components need to reflect the same changing data. It is recommended to lift the shared state up to their closest common ancestor.
Functional Components and Hooks: As of React 16.8, hooks were introduced which lets you use state and other React features without writing a class. It's recommended to use functional components over class components.
Key Prop in Lists: When rendering lists, always use unique keys. Keys help React identify which items have changed, are added, or are removed.
Event Handlers in JSX:
JSX uses camelCase naming for event handlers, rather than lowercase. For example, the HTML event onclick becomes onClick in JSX.
Lazy Loading and Code Splitting:
Large applications with many components can lead to slow initial load times. Using the React.lazy function allows you to render a dynamic import as a regular component.
This allows you to split your code into smaller bundles and load them on demand.
Using Fragments to Avoid Additional HTML Element Wrappers: React Fragments let you group a list of children without adding extra nodes to the DOM.
