🚀 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

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

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

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

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
