Iterables

JavaScript is special—it’s versatile, capable, and packed with tools that make life easier. One such tool is the concept of Iterables. You’ve probably used them without even realizing it. Remember that trusty for..of loop? Or how you’ve looped through an array or string? Behind the

Maps and Sets in Javascript

Before we get into conversions, let's understand why we have Maps and Sets in the first place. JavaScript developers traditionally use objects and arrays to store data, but these structures come with their own limitations: * Objects: Good for keyed collections, but restrict keys to strings or symbols. * Arrays:

Object to Primitives

Imagine you're trying to build a smart home. You've got objects representing everything—your fridge, your TV, even your coffee maker. But here's the thing, none of these objects can just magically interact. You can't add your fridge and TV together (although

Objects - Part 1

There are eight data types in Javascript, we have already discussed about the primitive data types in our previous lectures ( I would highly recommend reading them first if you haven't already ), and now we will discuss about the non-primitive data type - "Objects" Objects store data

Optional Chaining

The Problem Picture this: you're at a busy chai stall, trying to order your favorite masala chai. But wait! The stall owner is nowhere to be found. You can't just start brewing chai yourself, can you? That's exactly the kind of situation we find

Constructor-new

Alright, chai lovers and code enthusiasts! In this lecture we are going learn about constructors . Trust me, this is going to be more exciting than finding an extra samosa in your tiffin! The Birth of Objects: Constructor Functions Picture this: You're at a mithai shop, and you want

Objects and "this"

Objects are used to represent entities in the real world. When we need to create entities such as an animal object let animal = { name: "Rabbit", legs: 4 }; Here the object represents the entity "Rabbit" which is an animal. And the properties of the object represent the

Garbage Collection in Javascript

We have understood what memory is, and how memory is allocated and used in the previous article on Memory management in Javascript. Most of the memory leaks and memory issues happen because the allocated memory that is no longer in use is not disposed off but rather released as expected.

Memory Management in Javascript

Low-level programming languages require you to allocate and free up memory manually while high-level programming languages handle it for us. So, that brings the question, what is a "low-level" and "high-level" programming language? Low-level languages, such as Assembly or C, operate very close to the machine

Objects - Part 2

Let's do a quick recap about what objects are first! An object is a non-primitive datatype in javascript. Objects store data in a key-value pair format, where a value can be of any data type again and nested to "n" levels. Objects can be created with

Object References

Alright, let's dive into the world of Object references and copying in JavaScript! Buckle up, because this is as important as knowing the difference between paneer tikka and chicken tikka. Trust me, you don't want to mix those up! So, what's the big deal

Array Methods

Imagine you're preparing for a family function — let's say, a grand Indian wedding. You’ve got your guest list, which, of course, includes everyone from your childhood neighbors to your mom's best friend’s cousin's maid! Now, organizing this list, making edits,

In-Depth Javascript - Arrays

Definition: Arrays are special objects that store ordered data. Picture this- you’re organizing a wedding guest list (because let’s face it, in India, that can be a super-hard task!). You have your guests neatly lined up, and you want to keep track of their names. You could store

Data Types in Depth - Symbols

When we talk about data types in JavaScript, we often mention numbers, strings, booleans, or even objects. But there's one special data type that tends to fly under the radar—the Symbol. What is the "symbol" datatype? I am sure most of the experienced devs reading

Data Types in Depth - Null and Undefined

Coding in JavaScript can be fascinating once you know the gotcha's, the tricky parts in Javascript, one such concept in my opinion is the use of null and undefined especially in the initial stages of learning. At first glance, they might seem like twins – both representing the absence

Data Types in Depth - BigInt Data Type in JavaScript

In the wide landscape of JavaScript, where data types like strings, numbers, and Booleans play their roles, there’s a powerful "thing" known as BigInt. This data type was introduced to solve a particular problem: dealing with numbers too large to be accurately represented by the standard Number

Components of the Product

Creating a software product involves carefully considering various components that work together harmoniously. These components are the building blocks of the software and it is important to get them right to create a successful product. Ensuring smooth functionality, usability, and maintainability of the product while ensuring that it caters to

Data Types in Depth - Booleans

Whether you’re building a complex web application or just starting out, understanding how Booleans work is essential. Booleans represent the most basic form of data: true and false. In this article, we'll explore the Boolean data type in depth. What is a Boolean? In JavaScript, a Boolean

Datatypes in Depth - Strings

When we think about handling text in JavaScript, we're diving into the world of strings. Strings are everywhere in programming, whether you're building a website, writing an app, or even working with APIs. They represent textual data, and in JavaScript, they come with some unique features

Datatypes in Depth - Numbers

JavaScript, the language that breathes life into your web pages, is known for its dynamic and flexible nature. But this flexibility can sometimes be a double-edged sword, especially when it comes to dealing with numbers. Whether you’re calculating the bill for a street-side chai break or managing transactions in

Git: Crash course

Version control is a system that manages changes to files and code over time, allowing multiple people to collaborate on a project and track modifications. It helps you keep a history of changes, revert to previous versions, and resolve conflicts when multiple people make changes simultaneously. Imagine a PC game,

Introduction Functions in Javascript - Functions 1

In the world of JavaScript, functions are the main building blocks. They allow you to perform tasks and calculations without repeating code. Functions can be used to encapsulate code for reuse, making your programs more modular and maintainable. Let's dive into the essentials of JavaScript functions, excluding arrow

Common Mistakes with Loops

Loops are like the backbone of any programming language, and JavaScript is no exception. They allow you to automate repetitive tasks, just like how a busy Indian household might automate certain chores during a grand festival or wedding. However, just like in any large event, things can go wrong. Mistakes

Break, Continue, Return, and Throw in Javascript

When you’re deep into JavaScript, loops are your best friends. They help you repeat tasks without having to rewrite code, just like how you repeat certain rituals in Indian festivals. But what happens when you need to break away from a task, skip one, return early, or throw up

Data Types in Javascript

Remember the box of Laddus we had from the article "Variables in Javascript"? Let me quickly help you remember. A variable is like a box, an empty box, the data we assign to it is the content, just like a box and Laddus inside it! But do we
