JavaScript Ternaries Improve Code Readability

Hitesh Choudhary and Piyush Garg sir Let's Jot down the pen and paper , I have explained some of javaScript interview questions in between the assignment of cohort, even it was not the requirement of the assignment, i was not getting the readers, so i was thinking, if people will not read what they will miss. https://lnkd.in/grePCurS #chaicode #javaScript #js #operators

Object.groupBy() landed in native JS 2 years ago. It's time to drop that 'import _ from "lodash"' for grouping. Do you still use Lodash? If so, which methods stop you from dropping it, as it not really supported for a while now #javascript #lodash #webdev #mdn #groupBy

🚀 Accessing DOM Elements with JavaScript JavaScript provides several methods to access elements within the DOM. `document.getElementById()` retrieves an element by its unique ID. `document.querySelector()` returns the first element that matches a CSS selector, while `document.querySelectorAll()` returns a NodeList of all matching elements. Using these methods, you can target specific elements to modify their content, attributes, or styles. Understanding the nuances of each method is important for efficient DOM manipulation. #JavaScript #WebDev #Frontend #JS #professional #career #development

🧠 JavaScript Concept: Hoisting Explained Hoisting is JavaScript's behavior of moving variable and function declarations to the top of their scope before execution. This is why we can sometimes use variables or functions before they are declared. Example: console.log(name); // undefined var name = "Arun"; Why undefined? Because JavaScript internally treats it like this: var name; console.log(name); name = "Arun"; 🔹 Important Points: • "var" is hoisted and initialized with "undefined" • Function declarations are fully hoisted • "let" and "const" are hoisted but stay in the Temporal Dead Zone (TDZ) ⚠️ Accessing "let" or "const" before declaration will throw an error. 📌 Best Practice: Avoid relying on hoisting — always declare variables at the top for better readability. #javascript #frontenddevelopment #reactjs #webdevelopment #coding

🚀 Prototypal Inheritance (JavaScript) JavaScript uses prototypal inheritance, a mechanism where objects inherit properties and methods from other objects. Every object has a prototype, which is another object. When a property is accessed on an object, JavaScript first checks if the object itself has the property. If not, it looks up the prototype chain until the property is found or the end of the chain is reached. This allows for code reuse and creating hierarchies of objects. Understanding prototypes is essential for building complex object-oriented applications in JavaScript. The `__proto__` property (deprecated but still often seen) and the `Object.getPrototypeOf()` method are used to access an object's prototype. #JavaScript #WebDev #Frontend #JS #professional #career #development

Assalam o Alaikum, JavaScript Lesson 27: Default Parameters, Optional Chaining & Nullish Coalescing. This lesson covers safer, cleaner JavaScript patterns: default function values, safe access to nested properties with optional chaining (?.), and better fallbacks with nullish coalescing (??) instead of ||. I also show how to combine them in real-world code with user/theme examples.

🔥 Tricky JavaScript Async/Await Interview Question 🔥 What will be the output of this code? 👇 async function test() { try { console.log("1"); await Promise.reject("Error"); console.log("2"); } catch (e) { console.log("3"); } finally { console.log("4"); } } test(); console.log("5"); 💬 Drop your answer before checking 👇 #JavaScript #FrontendDevelopment #AsyncAwait #Promises #WebDevelopment #InterviewPreparation #ReactJS #CodingInterview #EventLoop #JavaScriptTips #SoftwareEngineering

⚠️ Part 2 of 10: I think `useEffect` gets overused. A lot. I get why. Something changes. You want something else to update. `useEffect` feels like the move. But a lot of React complexity starts right there. State changes. Effect runs. Another state changes. Now you're tracing logic across multiple places for something that maybe could’ve been calculated directly. Once I started asking: “Is this syncing with something external?” instead of “How do I make this run after render?” my code got a lot easier to follow. That one shift cleaned up a lot for me. What’s your most overused React habit? #React #useEffect #ReactHooks #FrontendDevelopment #JavaScript #TypeScript #CleanCode

📝 UseDefault Custom Hook React Custom Hooks allow developers to create logic with a specific purpose that can be reused within different components in their projects. This code section is an example of a custom Hook. In this example, a function named useDefault returns a default value when the state is either null or undefined. #React #SoftwareDevelopment #ReactHook #JavaScript

Day 11/21 – Creating Colorful Boxes with JavaScript Today I built a small interactive project using JavaScript. The idea was simple but fun: Whenever the user clicks a button, a new colorful box appears on the screen. Every click generates a new box, and the screen slowly fills with different colors. Concepts I practiced today: • JavaScript DOM manipulation • Click events • Dynamically creating elements using JS • Generating random colors • Updating the UI in real time What I realized today: JavaScript is what truly makes a website interactive. Without JS, a webpage is mostly static. Small experiments like this help me understand how the browser reacts to user actions.
