We may assume that our checkCount condition simply provides twice that is in the beginning on web page load and also when counter.value reaches 6 yet that is actually not real. For each time we operate our computed function our state re-renders which suggests our checkCount state makes 6 opportunities, at times influencing performance.This is actually where computedEager comes to our rescue.
