Did you know that Java behaves differently when comparing wrapper classes like Integer? 🤯 In this quiz, we test a simple line of code: Integer a = 128; Integer b = 128; System.out.println(a == b); Most beginners expect true, but the correct output is: ❌ 👇 Watch the video to learn why Java outputs false here! This happens because of Integer caching mechanism in Java — only values between -128 to 127 are cached. Anything outside that range creates a new object, so == compares references, not values. 🧠💡 --- 🎯 You'll Learn: ✔ Java wrapper class behavior ✔ Integer caching ✔ Difference between == and .equals() ✔ Common Java interview question --- 💬 Comment below: Did you get it right? 😎 --- 🔍 Keywords: Java quiz, Integer caching, Java interview question, wrapper classes, Java comparison, Java coding challenge, Java beginner tips, Java programming trick --- 📌 Hashtags: #Java #JavaQuiz #CodingQuiz #ProgrammerLife #JavaInterview #JavaTips #CodingChallenge #LearnJava #DeveloperCommunity #ProgrammingFacts #JavaDeveloper #CodeSmart #SoftwareEngineer #TechLearning #programminghumor

How to master JavaScript ↓ I get this question a lot: “𝗜 𝗱𝗼𝗻’𝘁 𝗸𝗻𝗼𝘄 𝗵𝗼𝘄 𝘁𝗼 𝘀𝘁𝗮𝗿𝘁 𝘄𝗶𝘁𝗵 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁.” 🙇🏻‍♂️ Maybe you’ve already started with HTML or CSS. But now, when it comes to actually building logic... 𝗬𝗼𝘂’𝗿𝗲 𝘀𝘁𝗿𝘂𝗴𝗴𝗹𝗶𝗻𝗴. That’s where most people get stuck 🚫 You’ve tried to find a way to understand the logic of it. But 90% of the tutorials out there are hard to follow. That’s why I’ve created a JavaScript cheat sheet with explanations. I show and explain the fundamentals of JavaScript and how to use them.

How much Javascript should you know before learning React ⚛️ React is a frontend library for developing JavaScript for browsers, therefore it makes sense to have a good grasp of Javascript first right? Outside of the basics of JS, such as data types, variables, functions etc, here’s a few topics to make sure you have a good grasp on: 1️⃣ Modules, import, export ⚙️ When working with React, you create your components in separate files, needing to compose them all together, including importing/exporting elements from one to another. Understanding how modules work is key! 2️⃣ Fluency with Array/Object methods 📚 Regardless of your app, you’re usually going to have to work with data of some sort, and operating on that data. Get familiar with array methods such as map, filter, reduce and immutable paradigms, as well as iterating objects as well. 3️⃣ Asynchronous Javascript 🔮 Learn how callbacks and promises work in Javascript, as well as async/await syntax. Fetching Data will come up and it’s important to understand the differences between how synchronous vs asynchronous functions resolve. 4️⃣ DOM Manipulation 🌲 At some point, you will end up needing to work on modifying the structure, style and content of the pages you build! You’ve got to understand how to create, access and remove elements, modify their content and know how to handle events. Yes you can learn Javascript by just focusing on React if that’s what you’re into! However, knowing more about JavaScript will make learning React easier and give you a better understanding of how things work under the hood! 🏎️ . . . . . #webdevelopment #webdeveloper #webdev #webdesign #html #html5 #css #css3 #js #javascript #react #reactjs #frontenddeveloper #frontend #dev #100daysofcode #coding #software #softwaredeveloper #peoplewhocode #code #programmer #programming #developer #learntocode

🔥 Day 36/50 — JavaScript Output Question That TRICKS Everyone! Most developers say the output will be: 0 1 2 But JavaScript says — NOPE 😅 Here’s the actual code: var funcs = []; for (var i = 0; i < 3; i++) { funcs.push(() => console.log(i)); } funcs[0](); funcs[1](); funcs[2](); 🎯 Actual Output: 3 3 3 😨 Why does this happen? Because: ✔️ var has function scope, NOT block scope The i inside the loop refers to the same variable every time. ✔️ Arrow functions capture i by reference, not value So when the loop ends: i = 3 And all 3 functions print the final value of i, not the value when they were created. 🧠 How to fix it? Use let instead of var: for (let i = 0; i < 3; i++) { funcs.push(() => console.log(i)); } Now output becomes: 0 1 2 💬 Comment below: Did you guess it right?
