💡 Solving the 0/1 Knapsack Problem using Dynamic Programming in JavaScript Recently, I implemented the 0/1 Knapsack problem using Dynamic Programming (DP). This classic optimization problem demonstrates how DP helps us efficiently make choices to maximize value while staying within constraints.💡 Solving the 0/1 Knapsack Problem using Dynamic Programming in JavaScript Recently, I implemented the 0/1 Knapsack problem using Dynamic Programming (DP). This classic optimization problem demonstrates how DP helps us efficiently make choices to maximize value while staying within constraints. 🧮 Problem: Given weights, values, and a capacity, choose items to maximize total value without exceeding the capacity. ⚙️ Approach: Use a 2D DP table dp[i][w] where each cell represents the maximum value for i items and weight w. Iterate through all items and capacities, deciding whether to include or exclude each item. 📘 Key takeaway: Dynamic Programming reduces redundant calculations and transforms exponential recursion into a polynomial-time solution.

What is JavaScript? JavaScript(high-level,interpreted programming language) is the programming language for web. It can update and change both HTML and CSS. It can change and manipulate data. https://lnkd.in/gKAGHkaU

Today I revised some important OOP(Object Oriented Programming) concepts in JavaScript -- and here is what I learned. 1. PROTOTYPES In JavaScript, prototypes allow one object to use the properties and methods of another object using" .__proto__ ". If both the object and it's prototype have the same method, the object's own method gets priority during execution. 2. CONSTRUCTOR The constructor is a special reserved keyword in JS classes. It automatically executes when an object is created, initialising it's properties right from the start. 3. INHERITANCE Inheritance helps a class use properties and methods from another class using the extends keyword -- like "class child extends parent". 4. SUPER KEYWORD When both parent and child classes have constructor, we use the super keyword in the child class to call the parent's constructor and pass it's parameters efficiently. Overall, this revision really helped me understand how JavaScript handles OOP behind the scenes and how flexible prototypes and inheritance make our code.

💭 Is HTML Really a Programming Language? A friend told me he’s learning programming. They started with JavaScript, now they’re on HTML, and soon, CSS. I paused and thought: Wait… HTML? A programming language? 🤔 Personally, I don’t think so. HTML (HyperText Markup Language) simply defines the structure of a webpage — headings, paragraphs, images, links, all wrapped in tags. It tells the browser what to show, not how to think. A true programming language, in my view, should have: Data types (strings, numbers, booleans) Data structures (arrays, objects, etc.) Logic — loops, conditions, functions, classes HTML doesn’t do any of that. It’s powerful, yes, but it’s markup, not logic. Funny enough, when I looked it up later, opinions were split — some say it is, others say it’s not.

One of the most valuable features of functional programming is the ability to work with lazy sequences. Today, nearly every programming language supports generics, functions as values, and iterators. These are essential building blocks for operators that work with lazy sequences. In the next series of posts, we will build my JavaScript library, powerseq, from scratch. https://lnkd.in/dTdM5snr
