HTML Custom Element Go-To-Definition Behavior

JavaScript Tip 💡: The easiest way to empty an array is to set its "length" to "0". This method is fast, simple, and effectively clears all elements. Watch the below video for a quick example 📹 Hope this helps ✅️ Do Like 👍 & Repost 🔄   #html #css #javascript #typescript #react

Started from console errors… Ended with a working calculator. 😄 Today I built a calculator using HTML, CSS & JavaScript. While building this, I learned: Why == behaves differently than === How JavaScript handles type coercion How to structure UI using Flexbox How to debug runtime errors effectively It’s a small project, but every small project builds big confidence.

This is how you can open any GitHub repository in VS Code directly in your web browser in less than 5 seconds 🤯 On any repository page, simply replace ".com" with ".dev" and you're all set ✅ Watch the below video for a quick example 📹 Do Like 👍 & Repost 🔄   #html #css #javascript #typescript #react

Got a minute for some JavaScript? ⌨️ What does this code output? Answer 🔍 >>> 105 When using *call*, all arguments after the first one are passed to the function parameters. Unlike *apply*, you don’t need to pass them as an array. Here, a single array [5] is passed, so a becomes [5]. When adding a number and an array in JavaScript, the array is converted to a string, and concatenation occurs. #javascript #webdevelopment

Day 6 – JavaScript Calculator Project Today, I worked on building a Simple Calculator using HTML, CSS, and JavaScript. What I practiced and learned: ✓DOM manipulation ✓JavaScript functions ✓Event handling (onclick) ✓Arithmetic operations (+, −, *, /, %) ✓Clear & Delete functionality #HTML #CSS #JavaScript #CalculatorProject #Day6 #FrontendDevelopment #Practice #LearningJourney

Today I practiced a small JavaScript program to change the background color when a button is clicked. When the button is pressed, JavaScript triggers a function that changes the page’s background color using DOM manipulation. This helped me understand: ✔ Event handling ✔ onclick function ✔ DOM manipulation ✔ How JavaScript interacts with HTML & CSS Small practice, better understanding 🚀 #JavaScript #WebDevelopment #Frontend #CodingPractice #LearningJourney

⚡ Day 3 – querySelector vs querySelectorAll (Real Difference) Both methods use CSS selectors. But they return different results — and that difference matters. 🔹 querySelector() ✔ Uses CSS selectors ✔ Returns the first matching element ✔ Returns a single element ✔ Stops after first match 🔹 querySelectorAll() ✔ Uses CSS selectors ✔ Returns all matching elements ✔ Returns a NodeList ✔ Can loop using forEach() 🧠 Key Difference: querySelector() → first match only querySelectorAll() → all matching elements ⚠️ Important: A NodeList is not an Array, but it supports forEach(). Understanding small DOM differences like this helps avoid common bugs and builds a strong JavaScript foundation. #JavaScript #WebDevelopment #Frontend #DOM #JSConcepts #Coding #100DaysOfCode

JavaScript Tip 💡:  Use the Array "at()" method to access last Array element easily! The "at()" method in JavaScript provides a simpler way to access elements in an array, especially the last one. Traditionally, getting the last element required using arr[arr.length - 1], but .at(-1) now handles this directly and more cleanly. With "at()", positive indices retrieve elements from the start, while negative indices count backward from the end. This makes .at(-1) a straightforward and readable alternative for accessing the last item in an array. Hope this helps ✅️ Do Like 👍 & Repost 🔄   #html #css #javascript #typescript #react

Got a minute for some JavaScript? 📏 What do you know about the length property of functions? Answers 🔍 >>> 3 1 1 You can remember it this way: The length property of a function equals the number of parameters before the first parameter with a default value. #javascript #webdevelopment
