So yeah… It’s been ages. But here I am, finally trying to start this. If not now, then. probably next year—or never. Honestly, I’ve just been vibing, scrolling, binge-watching “how to learn X in 10 minutes” videos, and pretending that counts as progress.

🚨 JIMS_GN College site redirects to an inappropriate page when opened via Google search. Just Look at the initiator chain in dev tools. Although Direct access is fine. Please fix it! .@JIMS_GN @jimsgn.@JIMSRohini .@jimsljptweets .@ugc_india.@AICTE_INDIA.@IndianCERT .@GoI_MeitY

It’s Day 12 of learning JavaScript, and I’ve realized I’m kind of stuck in tutorial hell.

💡 Nullish Coalescing Operator ??. Returns the right-hand value only if the left is null or undefined. let name = null ?? "Guest"; // → "Guest". 🔀 Ternary Operator. Shorthand if. else 💡. let age = 18;.let access = (age >= 18) ? "Allowed" : "Denied";.

✅ Check If the Array Is Empty. if (userEmail.length === 0) {. console.log("Array is empty");.}. ✅ Check If Object Is Empty. if (Object.keys(emptyObj).length === 0) {. console.log("Object is empty");.}.

⚠️ Falsy Values. In JS, these are considered false in boolean contexts:. false. 0. "" (empty string). null. undefined. NaN. Everything else is truthy.

⚖️ Comparison Operators. == vs === → loose vs strict equality. != vs !== → loose vs strict inequality. >, <, >=, <=. 🔐 Logical Operators. && (AND). || (OR). ! (NOT).

🔹 switch. Useful when comparing a single value to many cases. const day = Monday;.switch(day) {. case 'Monday':. console.log("Start of week");. break;. default:. console.log("Another day");.}.

🧠 Day 11: JavaScript Control Flow & Logical Operators. 🔁 Control Flow in JS. 🔹 if. if (true) {. // runs this block.}. 🔹 if. else. if (condition) {. // if true.} else {. // if false.}. 🔹 else if. if (a > b) {. }.else if (a === b) {. }.else {. }.

🧱 Behind the scenes:. GEC is created. one() context pushed → runs console.log. Calls two(), its context pushed. two() runs → pops off → back to one() → pops off → done ✅.

🔁 Example. function one() {. console.log("One");. two();.}. function two() {. console.log("Two");.}. one();. // Output: One → Two.

🔹 Call Stack (📞📚). JavaScript is single-threaded, so it uses a Call Stack to manage execution:. Global context gets pushed first. Each function call creates a new execution context that gets pushed on top. Once a function completes, it gets popped off the stack.

🔹 What happens during execution?. Whenever JS runs:. A new Execution Context is created. It consists of two components:. Variable Environment (includes variables, functions, and arguments). Thread of Execution (the single line in which code is executed).

Three types:. 🌐 Global Execution Context (GEC): Created when the JS file starts running. Only one exists. 🔁 Function Execution Context: Created whenever a function is invoked. 🧪 Eval Execution Context: Rarely used, created when eval() is called.

Okay, I didn't post yesterday, but I'm still consistent, and here is what I learned yesterday:. Day 10: How JavaScript Works Behind the Scenes 🛠️. 🔹 Execution Context: This is the environment where JS code runs.

✅ Arrow Function IIFE:. (() => {. console.log("Arrow IIFE running!");.})();. ⚠️ Notes:.IIFE creates a private scope. Variables inside the IIFE can't be accessed from outside.

🔸 Why Use IIFE?. Avoid polluting the global scope. Encapsulation—useful when you want to run some code privately. Common in module patterns. ✅ Example with Parameters:. (function (name) {. console.log(`Hello, ${name}!`);.})("Sagar");. // ➜ Hello, Sagar!.

(function () {. console.log("IIFE is running!");.})();. 🧠 The function is:. Wrapped in () to make it an expression. Immediately followed by () to invoke it.
