We can use the following approach in ReactJS to clear complete cache data. We can clear complete cache data from the browser as per the user requirement. Caching is a technique that helps us to stores a copy of a given resource into our browser and serves it back when requested.

Approach: Follow these simple steps in order to clear complete cache data in ReactJS. We have created our clearCacheData function which clears the entire cache data from the browser. When we click on the button, the function is triggered, and the entire caches get deleted from the browser and, and we see an alert popup. 

In the following example, we have 5 caches stored in the browser named CacheOne, CacheTwo, CacheThree, CacheFour, and CacheFive as shown below, and we clear the complete cache using our defined function.
