Same JavaScript Object… But Slower 😳 | Hidden Performance Trick

Description

Same JavaScript Object… But Slower 😳 | Hidden Performance Trick These two JavaScript objects look identical — but one is slower 🚨 In this short, I explain why object creation style affects performance and how JavaScript engines optimize objects internally. 🔹 Object literal vs step-by-step creation 🔹 Why loops expose performance differences 🔹 When this actually matters (and when it doesn’t) This is a micro-optimization, but understanding it makes you think like a senior JavaScript developer 💡 #javascript #advancedjavascript #performance #webdevelopment #coding #ytshorts #javascripttips #nodejs #frontenddeveloper #thecodingmonk #developers #programming
