How do you ref in react?
Refs are created using React. createRef() and attached to React elements via the ref attribute. Refs are commonly assigned to an instance property when a component is constructed so they can be referenced throughout the component.
How do you pass REF IN react?
React will pass the ref through and forward it down to <input ref={ref}> by specifying it as a JSX attribute. When the ref is attached, ref. current will point to the <input> DOM node. The second ref argument in the InputRef component only exists when you define a component with React.
What is ref in Div?
The ref attribute makes it possible to store a reference to a particular React element or component returned by the component render() configuration function. This can be valuable when you need a reference, from within a component, to some element or component contained within the render() function.
What is state in react?
React components has a built-in state object. The state object is where you store property values that belongs to the component. When the state object changes, the component re-renders.
What is lifecycle in react?
Lifecycle of Components
Each component in React has a lifecycle which you can monitor and manipulate during its three main phases. The three phases are: Mounting, Updating, and Unmounting.
Is setState asynchronous?
To update the state of a component, you use the setState method. However it is easy to forget that the setState method is asynchronous, causing tricky to debug issues in your code. The setState function also does not return a Promise.
What is hooks in react?
Hooks are a new addition in React 16.8. They let you use state and other React features without writing a class. Hooks are backwards-compatible. This page provides an overview of Hooks for experienced React users.
What are lifecycle hooks in react?
React class components can have hooks for several lifecycle events. Hooks allow function components to access them too, in a different way. During the lifetime of a component, there’s a series of events that gets called, and to each event you can hook and provide custom functionality.
What are the types of hooks in react?

Hooks Effect
- Updating the DOM,
- Fetching and consuming data from a server API,
- Setting up a subscription, etc.
Why hooks are used in react?
Hooks let us organize the logic inside a component into reusable isolated units: Hooks apply the React philosophy (explicit data flow and composition) inside a component, rather than just between the components. That’s why I feel that Hooks are a natural fit for the React component model.
Is react hooks the future?
React Hooks are a complete and better replacement for Classes. Before you say anything, yes, I am aware that React’s official documentation states that there are no plans to deprecate class components any time soon, so don’t worry, you don’t have to go out and re-write your entire code.
Is Redux needed with hooks?
If you have a use-case where you think you can contain ephemeral state to a single component, you can use the Redux architecture, but use the useReducer hook instead of using Redux to manage the state. If you later need to persist or share the state, you’re 90% done already.
What is JSX?
JSX stands for JavaScript XML. JSX allows us to write HTML in React. JSX makes it easier to write and add HTML in React.
Is JSX a HTML?
JSX is an XML/HTML-like syntax used by React that extends ECMAScript so that XML/HTML-like text can co-exist with JavaScript/React code. Unlike the past, instead of putting JavaScript into HTML, JSX allows us to put HTML into JavaScript.

Is JSX only for react?
Well it’s a big deal because it means JSX can be used without React. That was already true previously (Raphael Pombo does it in his article where he creates a React clone called Didact, and Preact also uses JSX), but now it’s made particularly easy, and this opens many doors.
How do I enable JSX in react?
To use JavaScript inside of JSX, you need to surround it with curly braces: {} . This is the same as when you added functions to attributes. To create React components, you’ll need to convert the data to JSX elements. To do this, you’ll map over the data and return a JSX element.

Can we use document getElementById in react JS?
By default, React does not provide direct access to underlying DOM elements. When working with DOM elements we use document. getElementById() function that returns a DOM element by its id. In React, if we‘d want to leverage the id property of elements we may end up with multiple HTML elements with the same id.
