What are some limitations of things you shouldn't do in the component's render method in React?

In React, the render method is crucial as it describes what the UI should look like for the component based on the current state and props. However, there are specific practices and operations that should be avoided within this method to ensure optimal performance and maintainability of the application. Here are some limitations and things you shouldn't do in the component's render method:

1. Avoid Complex Logic or Computations: The render method should be kept as simple and pure as possible. Complex logic, heavy computations, or side effects like data fetching or directly manipulating the DOM should be avoided. These operations can lead to performance issues because render can be called frequently and should be fast to execute[1][2].

2. Do Not Modify State: State should not be modified directly in the render method. State changes should be handled through setState() outside of render to avoid unexpected behavior and rendering loops. Modifying state directly in render can lead to infinite loops and performance degradation[1][2].

3. Avoid Conditional Rendering Using Multiple Return Statements: While conditional rendering is a common pattern, using multiple return statements in the render method can make the code harder to read and maintain. Instead, it's better to use conditional operators like ternary expressions or logical operators to handle conditional rendering within a single return statement[4].

4. Minimize Inline Function Definition: Defining functions inline within the render method, especially those passed as props to child components,...
