Java Full Stack Development - Day 15: Strings & Flexbox

New Blog Published: Understanding Object-Oriented Programming in JavaScript Object-Oriented Programming (OOP) is one of the most important concepts in software development. While learning JavaScript, understanding how classes, objects, and the four pillars of OOP work can greatly improve the way we structure and manage code. In this article, I explain: • What Object-Oriented Programming means • Classes and objects in JavaScript • The constructor method • The four pillars of OOP: Encapsulation, Abstraction, Inheritance, and Polymorphism • Simple examples to understand these concepts clearly My goal was to break down OOP in a simple and beginner-friendly way, especially for developers who are starting their JavaScript journey. I would really appreciate your feedback and thoughts.

Advancing in Java Full Stack Development – Strengthening Logic and Design Every Day #JAVA In today’s Java session, I revisited Abstraction and tried to connect it with the programming logic I practiced in the morning, like recursion-based sum problems, Fibonacci series flow, palindrome checking, swapping elements, and finding the second smallest number in an array. Understanding abstraction felt more meaningful because I could relate it to how we separate “what to do” from “how it works internally.” I strengthened my clarity on the difference between concrete classes and abstract classes, and how abstract methods act like a blueprint that child classes must implement. I also revised static and non-static members and understood their practical use while writing logic-based programs. The role of constructors became clearer as I realized how important initialization is when creating objects, just like properly setting up variables in logical problems. Combining conceptual OOPS knowledge with hands-on problem solving is helping me think more structured and confident in Java. In Web Technologies, I focused on CSS font properties and the overflow property. I explored how font-family, font-size, font-style, font-weight, and font-variant impact readability and overall UI appearance. Small styling changes can completely transform how a webpage feels to a user. I also understood how the overflow property (visible, hidden, scroll, auto) manages content when it exceeds container boundaries, which is very important for maintaining clean layouts. As I continue learning both backend logic and frontend styling together, I can see how each concept connects and builds toward becoming a complete Full Stack Developer. Consistency, practice, and clarity — that’s my focus every single day. 💪 #Java #OOPS #CSS #FullStackDevelopment #ProblemSolving #LearningJourney

Most of us use asynchronous programming in JavaScript almost every day. We use it to fetch data from databases, call APIs, or handle operations that might block the main thread. But how often do we stop and think about what actually happens behind the scenes? In this blog, I’m sharing my key learnings and breaking down the fundamentals of asynchronous programming in JavaScript.

Object-Oriented Programming (OOP) is one of the most important concepts in software development. Today, I strengthened my understanding of OOP in JavaScript by practicing: Classes Constructors Inheritance (extends) Parent constructor using super () Working with real examples like Employee and Manager classes helped me understand how real-world relationships are implemented in code. Here is a simple example I practiced: class Employee {   constructor(name, salary){     this.name = name;     this.salary = salary;   }   work(){     console.log(`${this.name} is working`);   } } class Manager extends Employee {   constructor(name, salary, department){     super(name, salary);     this.department = department;   }   manage(){     console.log(`${this.name} manages ${this.department}`);   } } let M1 = new Manager("Pankaj", 2000, "IT"); M1.work(); M1.manage(); OOP makes code more structured, reusable, and scalable.

Let’s talk about something that makes TypeScript feel almost like a programming language at the type level - 'Recursion in Mapped Types.' Imagine you have a deeply nested object type. Some properties are objects. Some are objects inside objects. Some are arrays of objects. Now your task is simple in words - 'Make everything optional. Even nested properties.' At first, this feels easy. We already know about 'Partial<T>' utility type. But 'Partial' only works at the first level. It does not go deep. Nested properties remain required. So how do we make everything optional at every level? This is where recursion comes in. In normal programming, recursion means a function calls itself. In TypeScript types, recursion means a type references itself inside its own definition. That’s it. So, how do we solve the problem with a deeply nested object? We can define a type that iterates over each property of an object, makes it optional, and if the property itself is an object, apply the same logic again. This 'apply the same logic again' part is recursion. But how does this even work? Here’s something fascinating about TypeScript. When a mapped type is applied to a primitive type like string or number, TypeScript simply returns that primitive type. It does not try to iterate over it. This behavior is intentional and baked into the type system. That’s why recursive mapped types don’t break when they eventually reach primitive properties. For example, when recursion hits 'string', it just stops naturally. That’s elegant. Recursion in mapped types is where TypeScript stops being static typing, and starts feeling like a type transformation engine. #Programming #TypeScript #JavaScript #WebDevelopment #Coding

In Java, the keywords 'const' and 'goto' are reserved even though they are not actually used in the language. This decision goes back to the early development of Java in the mid-1990s by James Gosling and the team at Sun Microsystems. In languages such as C and C++, const is used to declare variables whose values cannot change after initialization. Java, however, introduced the keyword final to provide immutability. Despite not implementing const, Java still reserves it so developers cannot use it as an identifier. This maintains familiarity for programmers coming from other languages and keeps the possibility open for future language changes. Similarly, goto was intentionally excluded from Java because it allows arbitrary jumps in code, which can lead to unstructured and difficult-to-maintain programs. Influenced by the structured programming movement and Edsger Dijkstra’s well-known criticism of the goto statement, Java’s designers encouraged clearer control flow using constructs such as loops, conditionals, and exception handling. However, the keyword goto remains reserved so it cannot be used as a variable or method name. A small real-world story made me appreciate this design decision even more. My teacher Syed Zabi Ulla shared an experience about his brother, who works as a backend freelancer. He received a project where the client wanted an existing backend codebase written in Java to be converted into C++. At first it sounded like a huge task, but because many programming languages maintain similar concepts, keywords, and structural patterns, the transition was much smoother than expected. He managed to complete the conversion in just four days. The consistency across programming languages made it easier for him to understand the structure, logic, and intent of the code. Design decisions like reserving familiar keywords contribute to this broader ecosystem of shared programming concepts. Benefits of reserving these keywords: • Maintains consistency with widely used programming languages. • Prevents developers from using these familiar terms as identifiers. • Preserves flexibility for potential future language features. • Encourages structured and maintainable coding practices. The presence of const and goto as reserved but unused keywords reflects Java’s design philosophy: clarity, maintainability, and long-term language stability. I shared the list of all the keywords in Java in the picture checkout if you want. #C++ #C #Java #programming #keywords

📘 Day 71: JavaScript OOPS (Object-Oriented Programming System) 🔹 What is OOPS? • OOPS divides a program into classes and objects • Helps in code reusability, better structure, and easy maintenance • Makes programs more organized and scalable 🔸 Class & Object • Class → Blueprint of an object • Object → Instance (example) of a class • One class can create multiple objects 💡 Example: • Class = House plan • Object = Actual house • Using one plan, we can build many houses 🔸 JavaScript OOPS vs Python OOPS • Concept is mostly the same • Differences: Python uses __init__() → JavaScript uses constructor() Python uses self → JavaScript uses this • JavaScript needs slightly more steps since this is used explicitly 🔸 Constructor • Automatically runs when an object is created • Used to initialize object properties • Defined using the constructor keyword 🔸 Methods in Class • Functions written inside a class are called methods • Can access class properties using this • Helps perform operations related to the object 🔸 Inheritance • Used to reuse code from an existing class • Achieved using extends keyword 🔹 extends • Allows a child class to inherit properties and methods from parent class 🔹 super() • Used inside child constructor • Calls the parent class constructor • Helps inherit values from parent class 🔸 Parent & Child Relationship • Parent class → Base class • Child class → Derived class • Child can access parent methods and properties ✨ Today you learned how OOPS works in JavaScript, including classes, objects, constructors, methods, and inheritance. This is a powerful concept widely used in real-world applications, frameworks, and large projects. #JavaScript #OOPS #Day71 #ObjectOrientedProgramming #ClassesAndObjects #Inheritance #JSDeveloper #FrontendDevelopment #LearningJavaScript #CodingJourney
