It is not possible for web browsers to read JSX directly. They are capable of reading only regular JS objects. As JSX is not a regular JavaScript object, it cannot directly be read by web browsers. A JSX file needs to be converted into regular JavaScript for a web browser to read it.

Here are a few major reasons why developers should choose ReactJS over other development frameworks:

Here are the major steps involved in creating a ReactJS application:

Synthetic events are the events that combine the response received from the native events of different browsers into a single API while making sure the events are consistent across multiple browsers. This ensures the consistency of an application irrespective of the browser it is running on.

In ReactJS, keys are unique identifiers that are used by developers to identify the items that are changed, updated, or deleted from the lists. They also help you determine the components that should be re-rendered instead of re-rendering all React components every time. This improves your web application’s performance by ensuring that only updated components are re-rendered.

In ReactJS, forms are used to interact with the application being built and enter necessary information whenever required. They contain a set of different elements like buttons, text fields, radio buttons, checkboxes, etc. Forms can be used for performing multiple tasks like ensuring user authentication, filtering, searching, indexing, and much more.

An arrow function is nothing but a shorter way to write a function in ReactJS. There is no need to bind ‘this’ within the React constructor while using an arrow function. This helps you prevent bugs caused due to the use of ‘this’ in the callbacks.

State refers to a built-in ReactJS object used for carrying data or information about the concerned component. The state within a component can change with time, re-rendering its component as it changes. The change in a ReactJS state can be triggered as a response to specific user actions or system-generated events. This change determines the component’s behavior and the way it will be rendered.

Props in ReactJS are short forms for properties. They are the built-in objects that store the value of attributes of specific tags and work just like HTML attributes. Props help developers pass data from one component to another. They are passed in the same way as arguments move within a function.
