The Problem

In our scenario, the goal is to perform animations in the hero section using framer-motion, but only during the first load of the application. Our want is to utilize local storage to track whether the animations should be displayed or not. Although the local storage is being updated accurately, the hero section does not reflect the correct state determined by useState and continues to play the animations regardless of the stored value.

Current Code Explanation

Here's a portion of the code that contributes to the issue:

On the first load, the state variable animate correctly reflects true, causing the animation to play. However, after updating the local storage, it continues to behave as if it hasn't changed at all.

The Solution

The solution involves a couple of essential adjustments to the original code to ensure it functions as intended. Here are the clear steps to follow:

Step 1: Remove async from the Function

One crucial adjustment is to remove async from the declaration of the Hero function. This is important because async functions return a promise instead of the intended JSX, which can lead to unexpected behavior.

Step 2: Simplify the Animation Logic

To ensure the animations respond correctly to the animate state variable, modify the effect and return structure of the component as follows:

What Changed?

Removal of async: By removing async, we ensure that the function behaves as intended and returns the correct JSX.

Animation Logic Simplification: The animation condition has been directly tied to the animate state, boosting clarity and reliability.

Final Thoughts

If you're encountering similar problems, ensure that your state variables are defined correctly and that you react to state changes properly within your components. This way, you can create smooth and effective user experiences in your applications!
