How to ensure hooks followed the rules in your project?

  • Use a linter plugin such as eslint-plugin-react-hooks
  • Use a testing framework to check for rule violations
  • Use a code review process to check for rule violations
  • All of the above
To ensure that hooks are being used correctly in a project, developers can use a linter plugin such as eslint-plugin-react-hooks to check for rule violations. They can also use a testing framework to check that the application behaves as expected when hooks are used. Finally, a code review process can help catch any rule violations before they are merged into the codebase.

What is children prop?

  • A prop that contains the child components of a component
  • A prop that contains the parent component of a component
  • A prop that is passed to the constructor() method of a component
  • A prop that is used to update a component's state
The children prop is a special prop in React that contains the child components of a component. It allows components to render their child components directly, without having to pass them down through props. The children prop can be used with any component, including functional components.

Why are Redux state functions called reducers?

  • Because they reduce the state of the application
  • Because they reduce the complexity of the application
  • Because they reduce the size of the application
  • Because they reduce the coupling between components
Redux state functions are called reducers because they take the current state of the application and an action as input, and return a new state as output. This process of reducing the state of the application is the core principle of Redux.

Does the statics object work with ES6 classes in React?

  • Yes, the statics object works with ES6 classes
  • No, the statics object only works with React.createClass()
Yes, the statics object works with ES6 classes in React. The statics object is used to define static properties for a React component, such as defaultProps or propTypes. In ES6 classes, you can define static properties using the static keyword, like so: 'static defaultProps = {...}'. This is equivalent to using the statics object in React.createClass().

What is the use of react-dom package?

  • To create React components
  • To handle routing in React components
  • To manage state in React components
  • To render React components to the DOM
The react-dom package is used to render React components to the DOM. The react-dom package provides several methods for rendering components, including the render method and the hydrate method.

What is an action in Redux?

  • A function that transforms the Redux store state
  • An object that describes a change in the Redux store state
  • A middleware function that handles asynchronous actions
  • A component that is rendered in response to user input
An action in Redux is an object that describes a change in the Redux store state. Actions are the only way to update the state of the Redux store, and they must have a type property that describes the type of action being performed. In addition to the type property, actions can also have additional data that is used to update the state.

How to create props proxy for HOC component?

  • By passing the additional props as arguments to the HOC function
  • By using the setState() method to add the additional props to the component's state
  • By using the this.props object to add the additional props to the component's existing props
  • By wrapping the component with another component that adds the additional props
To create a props proxy for an HOC component, you can wrap the component with another component that adds the additional props. This is done by defining a new component that takes the original component as input and returns a new component that includes the additional props.

What are the Pointer Events supported in React?

  • Both mouse and touch events
  • Mouse events only
  • None of the above
  • Touch events only
React supports both mouse and touch events through the use of Pointer Events. Pointer Events are a standardized event model that provide a unified way to handle mouse, touch, and stylus input. React provides a set of event handlers for Pointer Events, such as "onPointerDown" and "onPointerMove", that can be used to create responsive and touch-friendly user interfaces.

Is it possible to use React without JSX?

  • Yes, JSX is optional in React
  • No, JSX is required in React
JSX is a syntax extension for JavaScript that allows developers to write HTML-like syntax in their JavaScript code. While JSX is the preferred way to write React components, it is not strictly required. React components can also be written using plain JavaScript syntax, although this can be more verbose and difficult to read. However, JSX is widely used in the React community and is considered a best practice for writing React components.

What is the difference between super() and super(props) in React using ES6 classes?

  • There is no difference, they both call the superclass constructor
  • super() calls the superclass constructor, while super(props) passes props to the constructor
  • super() is only used in functional components
  • super(props) calls the superclass constructor, while super() passes props to the constructor
In React using ES6 classes, "super()" is used to call the constructor of the superclass, while "super(props)" is used to pass props to the constructor of the superclass. The "super(props)" syntax is necessary if you need to access props in the constructor of a subclass.
