🚨 JavaScript Interview Trap 🚨 What’s the output? 0 == false 0 === false "" == false null == undefined ❌ Many devs fail interviews here. 💡 Rule to remember: == → compares values (type conversion) === → compares value + type (no conversion) 👉 Always prefer === in real projects. Agree? Or still using == ? 👀 #JavaScript #InterviewQuestions #CleanCode #Developers
