How and When to Force React Re-Render

React provides a powerful mechanism called "rerendering" to update user interfaces based on component state, props, or context. There are scenarios where you need to force rerenders, such as external event changes, performance optimization, and third-party integration. Practical use cases include dynamic UI updates, conditional rendering, and animation effects, which can be achieved through code examples using useState, key prop, and context. This technique offers fine-grained control over component updates and performance optimization but should be used judiciously to avoid unnecessary overhead.
