Conditional Rendering of Components and Content in React

  In React, conditional rendering refers to displaying components or content based on state or props. This allows for a dynamic user experience, where visible elements can change depending on the conditions defined in the code.


Synopsis

  In React, we can use conditional rendering in different ways. Some common methods are:

  • Ternary operator: Used for a simple condition between two outcomes.

  • Short-circuiting (&&): Displays content only if the condition is true.

  • Prop-based rendering: Using props to determine which component to display.

Purpose

  Conditional rendering is key to creating dynamic interfaces in React. Depending on an application's state, we can display different views without directly modifying the HTML code.

  • Show components only if a specific condition is met.
  • Toggle between different views based on prop or state values.
  • Improve the user experience by displaying relevant or personalized content.
