React common syntax.
React is a popular J**Ascript library for building user interfaces. It provides a declarative way to build complex user interfaces. Here are some common syntax for React:
jsx syntax:
JSX is a unique syntax extension for React that allows you to write HTML-like markup in J.Ascript. It allows you to define the structure and style of components in jAscript. By using JSX, you can describe UI components more visually, rather than using pure JASCRIPT
For example: jsx copy**.
state:
In React, a state is a j**ascript object that stores a component's local data. By usingthis.stateDefine the state in the class component, or use itusestateHook defines the state in the function component.
For example: jsx copy**.
Props:
Props are parameters passed to a component to pass data from a parent component to a child component. In a child component, you can use properties to access the passed data.
For example: jsx copy**.
Event handling:
In React, you can use event handlers to handle user interactions, such as click events, input events, and more. Event handlers can be attached to a component through its properties and triggered when the user interacts with the UI.
For example: jsx copy**.
Conditional rendering:
Conditional rendering allows you to dynamically render different UIs based on conditions. In React, you can use:ifstatement orTernary operatorsto implement conditional rendering.
For example: jsx copy**.
