Type In Your Answers

We code by typing — so let's learn by typing. With CodeCode Ninja, you can set specific areas of a snippet of code you'd like to type in when you drill this card in the future. When the time comes, CodeCode Ninja will ask you to type in the answer and then rate yourself. You can use typing cards to master shell commands, Vim commands, and any other bit of code.

Keystroke Flashcards

We spend our days in a text editor or an IDE. So, learn to make the most of it — master all of your editor's hidden keyboard shortcuts, or craft entirely new ones and remember them forever. If you use Vim, you know what a huge difference this single feature can make in your productivity. And if you don't use Vim… well, you really should. Here's how keystroke cards work:

Multiple Placeholders Per Card

It's easy to use CodeCode Ninja to master multi-line code structures. Coding isn't all about one-liners: Context matters, so CodeCode Ninja lets you create a card with the complete structure, and mark out various areas of it for practice.

You Decide What Matters

With CodeCode Ninja, you start building out your own knowledge base. You decide which facts to put in — and for each fact, you decide how important it is. By explicitly setting a fact's importance, you give it context. Only you can do this — it's your own knowledge.
