Permit's check out at an excellent instance.counterIncrease.Greater than one hundred: checkCount
With our instance our experts notice that for checkCount to become real we will certainly need to click our boost switch 6 opportunities. We may believe that our checkCount condition simply leaves twice that is in the beginning on page bunch and when counter.value reaches 6 but that is certainly not true. For each time our team manage our computed feature our state re-renders which suggests our checkCount condition leaves 6 times, sometimes affecting efficiency.This is actually where computedEager relates to our saving.
