Container Component | Design Patterns in React
<p>In React, container components, also known as <strong>smart components</strong>, are a pattern used to separate concerns and manage the state and logic of a component. They serve as intermediaries between the data and the presentational components, often handling data fetching, state management, and passing data down to the presentational components as <strong>props</strong>.</p>
<p>The main idea behind container components is to keep the presentation logic and state management separate from the UI rendering. This promotes a more modular and maintainable codebase.</p>

<p>Container Components in Action </p>
<p><strong>Advantages:</strong></p>
<ul>
<li>Fetching the data once, it can be shared among all the children passed inside the container.</li>
<li>It leans more towards separating the concerns of managing data and presenting the data in the UI.</li>
<li>It increases the testability by facilitating separate testing of the container component’s data-related logic and the presentational component’s rendering behavior.</li>
</ul>
<p>We now have a high-level overview of what Container components are and why we want to use them.</p>
