We might assume that our checkCount state merely makes twice that is actually in the beginning on webpage tons as well as when counter.value comes to 6 but that is not true. For every opportunity we run our computed functionality our condition re-renders which implies our checkCount condition leaves 6 times, sometimes impacting performance.This is actually where computedEager pertains to our rescue.
