Rendering in React

Rendering in React refers to how components are loaded and displayed in the browser. There are three main types of rendering:

1. Bundling (Full Preloading):
React renders everything upfront when the app starts.The browser downloads all components at once.
Problem? If the app is large, it takes longer to load initially( Even if the user only visits "Home," the entire app is loaded).

2. Lazy Loading (On-Demand Loading):
React only loads the components when needed.Useful for rarely visited pages (e.g., settings, admin dashboard).

3.Conditional Rendering (Render Based on Conditions):
Like lazy loading, but based on logic inside the component.React decides at runtime whether to show or hide something.

Bundling ->It is typically handled when you import components at the top level of your file.

Lazy Loading (On-Demand Loading) -> This can be done using React.lazy() and Suspense to delay loading of components.

Conditional Rendering -> state is often used in conditional rendering because the conditions you're testing (like whether something should be displayed or not) typically depend on dynamic data that may change over time. State helps keep track of that dynamic data, which in turn determines what gets rendered.
However, it's not always necessary to use state for conditional rendering. You can also use other factors like props or even simple logic (without state) to conditionally render content.

_So in short:

Bundling imports and renders everything at the start.

Lazy Loading loads components only when needed.

Conditional Rendering determines what is shown based on logic at the time of rendering, but doesn't change how the components are loaded.
