React Props Conditionally Passed and Default Values

One of the biggest mistakes new developers make is skipping the documentation. Tutorials are helpful, but official documentation gives you the real understanding of how a framework or library works. When you read the docs, you learn: • Best practices • Real examples • Advanced features • Proper implementation Every great developer I know spends time in the documentation first. 💡 Pro tip: If you want to master tools like React, Next.js, or Vue, make documentation your best friend.

Nobody talks about the moment you finally understand the React rendering cycle. One day it just clicks. You stop fighting re-renders. You stop throwing useCallback at everything hoping something sticks. You stop questioning why your component is rendering three times on a single state update and start actually knowing why. That moment does not come from reading the docs. It comes from breaking something badly enough in production that you had no choice but to go deep. The virtual DOM is not magic. Reconciliation is not magic. The dependency array is not a suggestion. Once you internalize that React is just a function that runs on a schedule and decides what changed, everything else starts making sense.

Day-10/21 🎮 Built a Bubble Game while sharpening my JavaScript fundamentals! Every developer knows that strong fundamentals are the real power-ups in programming. So I recently built a Bubble Game where the objective is simple but addictive: 👉 Find and click the correct number before the timer runs out! While building this project, I practiced several core JavaScript concepts: 💡 Concepts Used DOM Manipulation Event Handling Random Number Generation Game Logic Implementation Timers with setInterval() Dynamic UI Rendering The game generates random bubbles, sets a target number, and challenges the player to score as many points as possible before the timer hits zero. Every correct click regenerates the board and updates the score. 🔥 Why this project matters to me Even though the game is built with JavaScript, projects like this strengthen the logic that I’ll later implement using React components and state management. So this project is not just a game — it’s another step in my journey toward becoming a better React Developer. 🚀 Always learning. Always building. #JavaScript #WebDevelopment #React #FrontendDevelopment #Coding #LearningInPublic #GameDevelopment #Developers #SheryiansCodingSchool #21DaysChallenge "Can you beat my score before the timer ends? 👀🎮"

When it comes to building forms in React, you probably know how tedious it can be to perform basic tasks like validating inputs, plus managing all the form and error state. ‎ ‎Perhaps the most user-friendly form library available today is React Hook Form. All the functionality that you need in a form library is provided in one simple hook, called useForm, and enables you to create forms as sophisticated as you like. ‎ ‎It takes control of managing our form state internally, gives us easy helpers to display errors for the appropriate input, and applies validation rules without any external libraries such as Yup — along with handling the submission of our form: ‎ ‎When it comes to building functional forms, you want a library that’s easy to use and does not add too much code to your components. According to these two criteria, React Hook Form is arguably the best React form library out there. ‎ ‎#reactjs #form #nexjs #reacthookform #javascript #programming ‎ ‎ ‎

💡 What is Event Parameter in React? When an event happens in React, React automatically passes an event object to the function. This event object gives details like: 👉 Which element triggered the event 👉 Input value 👉 Mouse position 👉 Prevent default behavior 📌 Example Uses: • Reading input values • Preventing form reload • Handling button clicks • Managing UI interactions ⚡ Event parameter helps you control user interactions precisely. Master this to write professional React logic.

Revisiting the JavaScript DOM (Document Object Model) today to strengthen my fundamentals. Sometimes the best way to move forward in development is to go back and revise the basics. While revising, I focused on: • What the DOM actually is • The core pillars of DOM manipulation • Handling multiple events • Selecting multiple elements efficiently • Using setTimeout and setInterval • Building small interactive examples Every time I revisit these concepts, I discover something new and deepen my understanding of how JavaScript interacts with the browser. Small steps every day toward becoming a better developer. 🚀 #javascript #dom #webdevelopment #frontenddevelopment #codingjourney #100daysofcode #programming #developerlife #learninginpublic

Understanding State and Props in React (Simple Explanation) If you are learning React, two concepts you must understand early are state and props. Props: Props are used to pass data from a parent component to a child component. They are read-only, which means the child cannot modify them. Example: A parent sends a user name to a child component. The child just displays it. State: State is used to store data inside a component. Unlike props, state can change over time. Example: A counter that increases when you click a button uses state. Key Difference: Props are external and immutable. State is internal and mutable. In simple words: Props = Data coming from outside State = Data managed inside the component Understanding this difference helps in building better and scalable React applications. #ReactJS #FrontendDevelopment #SolGuruz #WebDevelopment #JavaScript #Programming #SoftwareEngineering

While learning React, I recently explored what happens behind the scenes when the UI updates the concept of Reconciliation and the Diffing Algorithm. When a component’s state or props change, React does not immediately update the real DOM. Instead, it creates a new Virtual DOM tree and compares it with the previous one. This comparison process is called Diffing. React checks what actually changed between the two trees and then updates only those specific parts in the real DOM instead of re-rendering everything. This process of efficiently updating the UI is known as Reconciliation. For example, if only a text value changes inside a <p> tag, React updates just that node rather than rebuilding the entire DOM structure. This makes React applications fast and efficient. A couple of interesting things React assumes to make this process quicker: • Elements with different types create different trees • Keys help React track items in lists efficiently Understanding how React updates the DOM internally really helped me see why things like keys and component structure matter for performance. #React #JavaScript #WebDevelopment #FrontendDevelopment #ReactJS #Programming #LearningInPublic

🚀 React 19 just made our code cleaner! Did you know forwardRef is no longer needed in React 19? ✅ ref is now just a regular prop — no wrapper, no extra imports, no boilerplate! I recorded a short video breaking it down with a real example — triggering a Child button from a Parent using ref. 🎥 Watch the video to see it in action 💻 Code is live on my GitHub — link in comments! #React #React19 #JavaScript #Frontend #WebDevelopment #Programming #100DaysOfCode Small change, big improvement in developer experience. Love where React is heading! 💙
