JavaScript Classes Explained: Prototypes and Constructor Functions

Implemented Selection Sort in JavaScript, where the smallest element is selected in each iteration and placed at its correct position. A simple yet effective way to understand sorting fundamentals and in-place operations. #JavaScript hashtag#DSA hashtag#Algorithms hashtag#Coding hashtag#WebDevelopment

Day 2/100 of JavaScript 🚀 Today’s Topic: "let", "const", "var", hoisting and TDZ. "var", "let", and "const" are used to declare variables, but they differ in scope and initialization behavior - "var" is function-scoped and during the creation phase it gets initialized with "undefined", so it can be accessed before assignment. - "let" and "const" are block-scoped and are registered in memory during creation, but not initialized immediately. This leads to TDZ (Temporal Dead Zone) a phase where the variable exists in memory but remains uninitialized and cannot be accessed. Accessing "let" or "const" variables before initialization results in a ReferenceError. - "const" must be initialized at declaration and cannot be reassigned. - "let" allows reassignment but not redeclaration in the same scope. These differences make "let" and "const" more predictable and safer compared to "var". #Day2 #JavaScript #100DaysOfCode

🚀 Day 17/30 – slice() vs splice() in JavaScript These two methods look similar but behave very differently 👇 🔹 slice() Returns a new array Does NOT modify original array Used to extract elements 🔹 splice() Modifies the original array Can add/remove elements Used for updating the array 💡 In simple terms: 👉 slice = copy 👉 splice = change learn with w3schools.com #Day17 #FrontendDeveloper #JavaScript #InterviewPreparation #WebDevelopment #30DaysChallenge JavaScript Mastery

Day 1/30 Write a function createCounter. It should accept an initial integer init. It should return an object with three functions. The three functions are: increment() increases the current value by 1 and then returns it. decrement() reduces the current value by 1 and then returns it. reset() sets the current value to init and then returns it. #30DaysOfCode #JavaScript #LeetCode #WebDevelopment #ProgrammingChallenge #CodingLife

JavaScript Promise chaining vs async/await: Promise chains: → Harder to read → Error handling complex → Callback-ish Async/await: → Reads like sync code → try/catch works naturally → Easier debugging The choice is obvious. #JavaScript #AsyncJS #CleanCode

Hoisting is a behavior in JavaScript where variable and function declarations are conceptually moved to the top of their containing scope (either the global script or a specific function) during the compilation phase, before the code is actually executed. It is important to understand that your code isn't physically moved anywhere. Instead, the JavaScript engine allocates memory for variable and function declarations before it executes the code line-by-line. #javascript #hoisting #frontend #scripting

Practicing JavaScript Strings with a simple hands-on project 💻 Built a couple of small projects,out of them one is here 🔹 Convert text to UPPERCASE & lowercase 🔹 Remove extra spaces 🔹 Replace specific words dynamically This helped me improve my understanding of: ✔ String methods ✔ Regular expressions for cleaning text ✔ DOM manipulation & event handling #JavaScript #WebDevelopment #Frontend #CodingPractice #LearningJourney
