🚀 Thread: JavaScript Deep Dive 🤖
1️⃣ Primitive Data Types
👉 Primitive data types are immutable and include string, number, boolean, null, undefined, symbol, and bigint. Each type has unique properties and behaviors.
#PrimitiveDataTypes #javascript
Example:
let myString = 'Hello';
let myNumber = 42;
let myBoolean = true;
2️⃣ Hoisting
👆 During the compilation phase, declarations (not initializations) of variables and function declarations are moved to the top of their containing scope. #Hoisting
Example:
console.log(a); // undefined
var a = 5;
3️⃣ Document Object Model (DOM)
🌐 DOM is the API that allows JavaScript to manipulate HTML and CSS, essentially making your webpage dynamic. #DocumentObjectModel
Example:
document.querySelector("#myId").innerHTML = "Hello";
4️⃣ Closures
🔒 A function and its lexical environment bundled together. Closures allow data privacy and can be powerful when creating factories or partial applications. #Closures
Example:
function outer() {
let x = 10;
return function inner() {
console.log(x);
};
}
const myClosure = outer();
myClosure(); // Outputs: 10
5️⃣ Promises
🤞 Promises are objects that represent a future outcome. They are extremely useful for handling asynchronous operations like API calls. #Promises
Example:
fetch(url)
.then(response => response.json())
.then(data => console.log(data));
6️⃣ Async/Await
👌 A modern way to handle asynchronous operations. It makes your code look synchronous, thus making it easier to understand and debug. #AsyncAwait
Example:
async function fetchData() {
const res = await fetch(url);
const data = await res.json();
console.log(data);
}
7️⃣ IIFE (Immediately Invoked Function Expressions)
⚡ An older but still relevant pattern to create a new lexical scope. This is often used to avoid global scope pollution. #IIFE
Example:
(function() {
var privateVar = 'I am private';
console.log(privateVar);
})();
8️⃣ Currying
🍛 Currying transforms a function with multiple arguments into a series of nested functions with a single argument. It's helpful for creating partial applications. #Currying
Example:
const add = a => b => a + b;
const addFive = add(5);
console.log(addFive(3)); // Outputs: 8
9️⃣ Inheritance
👨👩👦 JavaScript supports prototypal inheritance. ES6 introduced the class syntax which is syntactic sugar over this mechanism. #Inheritance
Example:
class Animal {
makeSound() {}
}
class Dog extends Animal {
makeSound() {
console.log("Woof");
}
}
🔟 Polymorphism
🔁 Different objects can be treated as objects of their parent class, allowing the same code to work with objects of different classes. #Polymorphism
Example:
class Cat extends Animal {
makeSound() {
console.log("Meow");
}
}
1️⃣1️⃣ Call Stack
📚 JavaScript uses a call stack to manage function execution. When a function is called, it is added to the stack; when it returns, it is removed. #CallStack
Example:
function a() { b(); }
function b() { c(); }
function c() { console.log("Stack"); }
1️⃣2️⃣ Encapsulation
🔐 The bundling of data and methods that operate on that data. It restricts direct access to some of the object's components, protecting the internal state. #Encapsulation
Example:
class Car {
constructor(make, model) {
this._make = make;
this._model = model;
}
get description() {
return `${this._make} ${this._model}`;
}
}
1️⃣3️⃣ Recursion
🔄 A function calling itself. Recursive functions are particularly useful for tasks like traversing tree-like structures. #Recursion
Example:
function factorial(n) {
if (n === 0) return 1;
return n * factorial(n - 1);
}
🎯 Conclusion
JavaScript's complexity ranges from basics like primitive types to advanced topics like recursion and encapsulation. Being proficient in these topics is key to becoming a JavaScript expert. 🛠

R4 D49-Sleepy 🧠after work but dipped my toe in refresh on the #MathObject. Will get more into it tomorrow. Went over how strings, numbers and booleans are #PrimitiveDataTypes, basic values built into the language. Time to get some rest after 🏠of🔥🐉 #100DaysOfCode #100Devs 🙏🏾😴
