Either: Errors as Values, Not Explosions (Part 5 of the Functional Programming Series)

Part 5 of the Functional Programming in Practice series. Part 4 killed null with Option. But Option tells you a value is missing without telling you why. This part fixes that, and turns errors into honest values. Hey there, Coding Chefs! 👨‍💻 Let me tell you about a 2am page I

Killing null: Option and Maybe for the Billion-Dollar Mistake (Part 4 of the Functional Programming Series)

Part 4 of the Functional Programming in Practice series. Parts 1 through 3 built pure pipes, composition, and recursion. Now we use all of it to remove the single most common crash in software. Hey there, Coding Chefs! 👨‍💻 Quick question. What is the most common runtime error you have ever

Recursion and Immutable Data: Writing Loops Without `for` (Part 3 of the Functional Programming Series)

Part 3 of the Functional Programming in Practice series. Parts 1 and 2 covered pure pipes and how to compose them. Now we deal with the thing that makes most people think functional programming is insane: there are no loops. Hey there, Coding Chefs! 👨‍💻 The first time someone told me

Function Composition and Currying: Building Big Pipes From Small Ones (Part 2 of the Functional Programming Series)

Part 2 of the Functional Programming in Practice series. Part 1 set the foundation: types are sets, functions are pipes, and a pure function is Total, Deterministic, and free of side effects. This part is about welding those pipes together. Hey there, Coding Chefs! 👨‍💻 Have you ever written code that

The Honest Definition of Functional Programming: Types as Sets, Functions as Pipes, and Why Purity Pays (Part 1 of the Functional Programming Series)

Part 1 of the Functional Programming in Practice series. All TypeScript, no Haskell required, no burritos. Hey there, Coding Chefs! 👨‍💻 Ask a programmer "do you use functions?" and you'll get a funny look. "Obviously. I've got a function to fetch the time, one

Building a Reusable AI SDK

Recently, I’ve found myself building AI enabled applications, like the AI content optimization platform “https://buffbyteai.xyz/” and a Anaemia detection using computer models https://nailtechapp.netlify.app/, some of my major problems is managing the api keys for my LLM providers, dynamic prompts, variable prefill, AI persona’s,

Hey there, fellow Coding Chefs! 👋 You've shipped a beautiful product. The animations are smooth, the gradients are great, the Lighthouse performance score is a proud 94. Marketing is happy. Your PM is already talking about the launch tweet. You close your laptop feeling like a rockstar. Then Monday

JavaScript Temporal Dead Zone and Variable Declarations

Part 3 of the JavaScript Deep Dive Series In our previous article, we learned that JavaScript has a compilation phase where it scans through your code and sets up variable declarations. But not all variable declarations behave the same way during this process. Understanding the differences between var, let, and

JavaScript Lexical Scope and Compilation

Part 2 of the JavaScript Deep Dive Series Before JavaScript executes a single line of your code, something crucial happens behind the scenes. While most developers think JavaScript executes and runs code line by line(I know I mentioned this in the first series), the reality is more sophisticated and

JavaScript's Thread of Execution - How Code Really Runs

Part 1 of the JavaScript Deep Dive Series Welcome to JavaScript Deep Dive - a comprehensive series where we'll journey through JavaScript's inner workings, one concept at a time. Over the next several articles, we'll explore everything from basic execution to advanced patterns like
