Kata Ranking (kyu)

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.

4 kyu kata represent a competent programming level.

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

5 kyu kata represent a novice programming level.

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

6 kyu kata represent a novice programming level.

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

7 kyu kata represent a beginner programming level.

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

8 kyu kata represent a beginner level.

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
