ReactJs Expert-React.js development assistant

Example

A developer needs a reusable button component with custom styling and props.

Scenario

ReactJs Expert can generate a functional and styled button component, explaining each part of the code. For instance: ```jsx const CustomButton = ({ onClick, label, style }) => ( <button onClick={onClick} style={style}> {label} </button> ); ``` This snippet includes props for handling click events, labels, and custom styles.

Example

A developer encounters an error with state management in a React component.

Scenario

ReactJs Expert can identify common pitfalls such as incorrect state updates or improper use of hooks. For example, if a developer is incorrectly using the `useState` hook inside a loop, ReactJs Expert can pinpoint the issue and suggest placing the hook at the top level of the component to ensure correct functionality.

Example

A developer is confused about the lifecycle methods in class components.

Scenario

ReactJs Expert can provide a detailed explanation of lifecycle methods such as `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`, complete with practical use cases. For example, explaining how `componentDidMount` is used for fetching data after a component has been rendered: ```jsx componentDidMount() { fetchData().then(data => this.setState({ data })); } ```
