List of TypeScript Kata to Update - codewars/content-issues Wiki

We have TypeScript kata stuck in 2.x that must be updated before adding a newer version.

Background

Since TypeScript 3.x, we changed to use --strict and stopped concatenating with the optional preloaded code.

After running a script to automatically update existing kata, we found that most of them are written like JavaScript (contains implicit any in reference solutions or test helpers). Also, many of them doesn't follow best practices (e.g., unnecessary class with static method is exported).

How to Update

Use the new "Fork" feature to update kata:

You don't need to open an issue/suggestion and wait to edit. Forking a kata in a language is similar to forking an approved translation, but better because

all languages can be forked, including those added directly in Kata Editor and the original language
it's never outdated because it forks from the kata

You should see "Fork" when viewing a kata with the language you've completed in selected. Click that to open a translation editor with the current version filled in. The proposed changes can be merged or rejected after publishing, just like translations.

If there's a /// <reference comment, remove them as well. For most errors, solutions shouldn't be invalidated if it's written properly.

If a kata uses preloaded code, it needs to be imported explicitly (import { foo } from "./preloaded"). This might invalidate solutions depending on the usage.

Also, consider fixing unidiomatic TypeScript:

Using static methods in unnecessary class instead of simple function.
Extending prototypes of builtins

Don't worry about invalidating solutions.
