Dynamic Rendering

J20 provides the Replace component for dynamic rendering. When the of value changes, the internal content is unmounted and rebuilt. Used for scenarios requiring large-scale reconstruction.

Basic Usage

import { Replace } from "j20";

let $value = 1;

<Replace of={$value}>
  {/* Content related to $value - use function to get value (value is a regular snapshot) */}
  {(value) => <div>{value}</div>}
  {/* Content unrelated to $value - renders directly */}
  <div>Some</div>
</Replace>;

Use Cases

The Replace component is suitable for:

• Scenarios requiring complete component tree reconstruction
• Scenarios requiring cleanup of previous state
• Switching between multiple different components
