source: Codewars Wiki Honor & Ranks and Codewars Wiki Kata Ranking
Ranks are used to indicate progression and difficulty. Code Warriors complete Kata which are assigned a rank, which in turn earns them a higher rank once they complete enough of them. There are two classes of ranks, Kyu and Dan. You begin with Kyu at level 8 and work your way down to level 1. Then you progress to Dan, where you work your way up from level 1 to level 8.
At this level the kata begin to take some serious thought to complete. They include tasks that may handle:
- Computer science concepts utilizing complex algorithms
- Advanced design patterns
- Understanding intricate business requirements
- Advanced concepts such as concurrency, parallelism, meta programming and cryptography
At this level the kata are similar to 6 kyu but more challenging. It includes:
- Complex language features that require mature OOP/Functional concepts
- Advanced OOP/Functional concepts
- Complex Design Patterns
- Advanced regular expression usage
At this level the kata will start to include more advanced algorithmic challenges and more complex language features. It includes:
- Complex language features (closures, scopes, monads, etc)
- Complex OOP/Functional concepts
- Basic Design Patterns
- Complex Regular Expressions
At this level the kata will generally challenge users on their core language and API reference knowledge. Tasks such as:
- Iterating arrays and returning a subset of values
- Basic data type manipulations
- Basic functional or object-oriented concepts
- Basic Regular Expressions
At this level the kata is only challenging for users new to programming. This includes programming tasks such as:
- Defining a simple function (i.e. hello world)
- Basic variable assignments
- Fixing basic syntax issues
- Trivial algorithms such as basic if/else statements
