🚀#Web_Development :-101 days coding challenge 🚀 #Day- 38🔥 🙏Hello connection’s 🙏 🌟 **This is a Day 38of My Sigma WebDev Journey: JavaScript- Selecting by IDs, Classes, and more 🌟 In JavaScript, selecting HTML elements is a common task when you want to manipulate or interact with the DOM (Document Object Model). 🔻Here’s a quick guide on how to select elements using IDs, classes, and other methods.🔻 1️⃣Selecting by ID : - 🔸**Method**: `document.getElementById('id')` 🔸 **Usage**: Selects a single element with a specific `id` (IDs should be unique). ⚡️javascript⚡️ const element = document.getElementById('myId'); 2️⃣Selecting by Class : - 🔸 **Method**: `document.getElementsByClassName('className')` or `document.querySelectorAll('.className')` 🔸**Usage**: Selects elements with a given class name. - `getElementsByClassName` returns an HTMLCollection (live). - `querySelectorAll` returns a NodeList (static). ⚡️javascript⚡️ const elements = document.getElementsByClassName('myClass'); const elements = document.querySelectorAll('.myClass'); 3️⃣Selecting by Tag Name : - 🔸**Method**: `document.getElementsByTagName('tagName')` 🔸**Usage**: Selects all elements with a specified tag name. ⚡️javascript⚡️ const elements = document.getElementsByTagName('p'); 4️⃣Selecting with CSS Selectors : - 🔸**Method**: `document.querySelector('selector')` or `document.querySelectorAll('selector')` 🔸 **Usage**: Selects elements based on CSS selectors. - `querySelector` returns the first matching element. - `querySelectorAll` returns all matching elements. ⚡️javascript⚡️ const firstElement = document.querySelector('.myClass'); const allElements = document.querySelectorAll('div > p'); 5️⃣Selecting by Attribute : - 🔸**Method**: `document.querySelector('input[name="attributeValue"]')` or `document.querySelectorAll('input[name]')` 🔸 **Usage**: Selects elements based on their attributes. ⚡️javascript⚡️ const input = document.querySelector('input[name="username"]'); 🔻Summary🔻 🔹**getElementById**: Selects a single element by its unique ID. 🔹**getElementsByClassName**: Selects all elements with a given class name. 🔹**getElementsByTagName**: Selects all elements with a given tag name. 🔹**querySelector**: Selects the first element that matches a CSS selector. 🔹**querySelectorAll**: Selects all elements that match a CSS selector. These methods provide flexibility in how you can select and manipulate elements within your web pages. #HTML #CSS #Java_Script⚡️ #LearningEveryDay #FrontendDevelopment😍 #WebDevelopment #CodingJourney #Sigma_Web_Development_Course🧑‍💻🚀 #You_tube

🚀 Day 12/30 of the DSA Challenge 🚀 Today, I dive deep into the world of singly linked list. I have explore more problems with different approach and new concepts. Consistency is proving to be the most rewarding aspect of my journey! 🔄 Previous Revision + Problems Solved 🔄 Merging Two Sorted Linked Lists into One: Combining two sorted lists into a single, streamlined sorted list. Merging Multiple Sorted Linked Lists into One: Tackling the challenge of merging multiple sorted lists while maintaining order. Finding the Middle Element of a Linked List: Implementing efficient algorithms to pinpoint the exact middle of the list. Cycle Detection in a Linked List: Utilizing advanced techniques to determine if a linked list contains a cycle, a crucial skill for list manipulation. This marks Day 12 of my 30-day DSA challenge. The journey has been incredibly enlightening, and I'm thrilled to continue exploring more data structures and algorithms in the days ahead. Let's keep pushing the boundaries and growing together! 💪✨ #dsa #30daydsachallenge #cpp #striverdsasheet #linkedlist #coding #programming #learning #growth

🚀 Day 12 of my DSA Challenge 🚀 Today, I tackled the Set Matrix Zeroes problem! 🔢 The task was to efficiently set entire rows and columns to zero if an element in the matrix is zero. While it seemed tricky at first, breaking it into smaller steps and optimizing the approach helped me achieve an efficient solution! ✅ Key takeaways: Reinforced my understanding of array manipulation and problem-solving strategies. Every day in this challenge brings new learning, and I'm loving the process! 💻 If you're also solving DSA problems, let me know in the comments—let's share ideas and grow together! 🙌 #DSAChallenge #ProblemSolving #CodingJourney #NeverStopLearning

Day 15 of the #100DaysOfCode Challenge ✅ Solved 2 DSA problems ✅ Revised MERN concepts ✅ Continued working on my React project ❌ Still struggling with the ECE final year project research Another productive day focusing on both DSA and MERN revision. I’m making good progress in my web development journey, but still need to crack the right project idea for my ECE final year work. Any tips or suggestions are appreciated! #WebDevelopment #React #MERN #DSAPractice #CodingJourney #InterviewPrep #100DaysOfCode #ECE #WirelessCommunication #Electronics #TechLearning

🚀#Web_Development :-101 days coding challenge 🚀 #Day- 30🔥 🙏Hello connection’s 🙏 🌟 **This is a Day 30 of My Sigma WebDev Journey: JavaScript Object’s !** 🌟 In JavaScript, an object is a data structure that allows you to store and manage data in key-value pairs. Each key in an object is a string (or Symbol), and the corresponding value can be any data type, including other objects or functions. Objects are fundamental to JavaScript and are used to represent and manipulate collections of related data. 🔻Here's a quick overview of JavaScript objects:🔻 1️⃣Creation : - You can create objects using either object literals or the `new Object()` syntax. - **Object Literal**: - ⚡️javascript⚡️ let person = { name: "Alice", age: 30, greet: function() { console.log("Hello, " + this.name); } }; - **Constructor**: ⚡️javascript⚡️ let person = new Object(); person.name = "Alice"; person.age = 30; person.greet = function() { console.log("Hello, " + this.name); }; 2️⃣Accessing Properties : - You can access object properties using dot notation or bracket notation. - **Dot Notation**: ⚡️javascript⚡️ console.log(person.name); // Subhash - **Bracket Notation**: ⚡️javascript⚡️ console.log(person["age"]); // 24 3️⃣Adding/Modifying Properties : - ⚡️javascript⚡️ person.name = "Bob"; // Modifies existing property person.job = "Engineer"; // Adds new property 4️⃣Deleting Properties : - ⚡️javascript⚡️ delete person.job; 5️⃣Methods : - Objects can have functions as properties, called methods. ⚡️javascript⚡️ person.greet = function() { console.log("Hello, " + this.name); }; 6️⃣Inheritance : - Objects can inherit properties and methods from other objects via prototypes. ⚡️javascript⚡️ let animal = { speak: function() { console.log("Animal speaks"); } }; let dog = Object.create(animal); dog.bark = function() { console.log("Woof!"); }; dog.speak(); // Animal speaks dog.bark(); // Woof! 7️⃣Prototypes : - Every JavaScript object has a prototype object from which it inherits properties and methods. 8️⃣Built-in Objects : - JavaScript has several built-in objects, such as `Object`, `Array`, `Date`, and `Math`, which provide additional functionality. Objects are a powerful and flexible way to manage and organize data and functionality in JavaScript programs. #FrontendDevelopment😍 #HTML #CSS #UIUX #Java_Script⚡️ #Js_Objects⚡️ #LearningEveryDay #WebDevelopment #CodingJourney #Sigma_Web_Development_Course🧑‍💻🚀 #You_tube

#day44 of #50daysofcodechallenge - Webdevelopment ( #javascript ) I am happy 😍 to announce that today I have completed some topics in javascript. JavaScript For In : The JavaScript for in statement loops through the properties of an Object: Syntax : for (key in object) {   // code block to be executed } For In Over Arrays : The JavaScript for in statement can also loop over the properties of an Array: Syntax : for (variable in array) {   code } Do not use for in over an Array if the index order is important. The index order is implementation-dependent, and array values may not be accessed in the order you expect. It is better to use a for loop, a for of loop, or Array.forEach() when the order is important. Array.forEach() : The forEach() method calls a function (a callback function) once for each array element. Example : const numbers = [45, 4, 9, 16, 25]; let txt = ""; numbers.forEach(myFunction); function myFunction(value, index, array) {  txt += value + " "; } // output: 45 4 9 16 25 JavaScript For Of : The JavaScript for of statement loops through the values of an iterable object. It lets you loop over iterable data structures such as Arrays, Strings, Maps, NodeLists, and more: Syntax : for (variable of iterable) {   // code block to be executed } Get started with Web Development At #w3schools. That's all for today!!! Happy Coding! 💻 ✌ #w3schools #javascript #learning #webdevelopment
