Implementing Selection Sort in JavaScript

🚀 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 3/100 of JavaScript 🚀 Today’s Topic: "use strict" "use strict" enables strict mode in JavaScript, which makes the code run in a more controlled and error-prone way by enforcing stricter rules - Variables must be declared before use - Using undeclared variables throws a ReferenceError - Duplicate parameter names are not allowed - this in functions (non-methods) is undefined instead of the global object. It helps catch common mistakes early and prevents unsafe actions in the code Strict mode can be applied to: - Entire script - Specific functions Using strict mode improves code quality, predictability, and makes debugging easier #Day3 #JavaScript #100DaysOfCode

Ever wondered why changing employee1 also changes employee in JavaScript? 🤯 It’s the classic Reference Trap—objects are stored in the heap, and the = operator only copies the reference, not the object itself. In my latest video, I break down how memory references work and why mastering Pass by Reference is key to writing bug-free code. 👉 Watch the full explanation and level up your JavaScript skills! 🎬 #JavaScript #CodingTips #WebDevelopment #ProgrammingConcepts

Continuing my Frontend revision, sharing my handwritten notes on JavaScript concepts. While learning JavaScript, I realized how important it is to understand how strings and arrays actually work. These cover string methods, method chaining, arrays, array methods, and basic operations on arrays. Sharing in case it helps anyone learning JavaScript fundamentals.

In this Postman Tutorial, we will learn about variables in JavaScript. In order to do API test automation with Postman we need to learn JavaScript for API testing. As Postman tool supports JavaScript so we can write automated API tests in Postman using JavaScript. https://lnkd.in/drHCD477 #PostmanTutorial #javascript #javascriptforbeginners #PostmanAPITesting #ApiTesting #API #apiautomation #RcvAcademy #SoftwareTestingMentor

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

🚀 Day 15/30 – Event Bubbling in JavaScript When an event occurs on an element, it doesn’t just stop there — it bubbles up through its parent elements all the way to the root. 👉 Simply put: Event starts from the target element → moves up to parent → ancestor → document 💡 Example: Clicking a button inside a div will trigger: Button’s event Then the parent div’s event Learn with JavaScript Mastery #Day14 #FrontendDeveloper #JavaScript #InterviewPreparation #WebDevelopment #30DaysChallenge w3schools.com

JavaScript becomes a different language the moment you realize this: 👉 Functions are not just reusable blocks… they are values. And once you understand that, concepts like callbacks and higher-order functions stop feeling confusing and start feeling natural. In this video, I’ve broken it down step by step: How values behave in JavaScript How objects behave Why functions behave the same way (and why that matters) From there, everything builds logically: ✔ Passing functions as arguments ✔ Returning functions from functions ✔ What exactly a callback is ✔ What a higher-order function is ✔ How this leads to more flexible and reusable code No jargon. No unnecessary complexity. Just a clear, practical approach to a core JavaScript concept. 🎥 Watch here: https://lnkd.in/gM8ibZ6M This is Part 1 — next, we’ll explore how this shows up in real code with: setTimeout, forEach, map, filter #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #JavaScriptDeveloper #SoftwareDevelopment #Developers #CodingJourney #TechEducation #Hosiyar #JS
