Codewars TypeScript Solutions

A collection of my Codewars challenges.

Codewars is a great platform to sharpen problem-solving skills through short coding challenges called katas, in a more gamified format that offers a different type of problem than what you typically deal with studying front-end development.

It ranks katas and your own skill by a kyu system — the more katas you solve, the higher you climb, similar to a leveling system.

It's also a way to practice TypeScript in a more abstract way, engaging with a different side of the language and its mechanics than day-to-day front-end work usually calls for.

Exercises

Kyu reference

Codewars ranks problems from 8 kyu (easiest) to 1 kyu (hardest) - although that's quite relative. I'm starting at 8–7 kyu to build confidence with the platform and TypeScript syntax, then moving up as it makes sense.

Rank	Rough equivalent
8–7 kyu	Syntax, basics, simple logic
6–5 kyu	Algorithms, data structures
4–3 kyu	Complex problem solving
2–1 kyu	More advanced algorithms

Approach

• Language Mastery: Deepening my understanding of TypeScript features, strict typing, interfaces, and advanced utility types.
• Algorithmic Thinking: Learning more about algorithms, Big O and problem-solving strategies.

Project Structure

Each kata folder contains

• README.md — the original problem statement
• solution.ts — my solution (sometimes multiples solutions)

Coding Philosophy

When solving these Katas, my priority is readability and maintainability over "clever" one-liners. Learning the different applications of the language.
