Codewars

Because you read this, I assume you have nothing to do and you must be really bored as well. If this is the case, go on codewars.com.

But wait. I'd really like to give you a quick overview about this Gem.

What is Codewars?

In one sentence I'd describe Codewars as an addictive and challenging, programming training plattform on the web.

What can you do on Codewars?

Codewars is based on a ranking system. You can achieve higher rankings through solving katas (the challenges).

At the moment you can solve your katas in this programming languages

• JavaScript
• CoffeScript
• Ruby

Others will follow (reffering to Codewars).

Example Challenge

Here's an example challenge. A very easy one. It's classified at 8 Kyu's (difficulty) which is the lowest level. We have a technicall math problem which depens on the rule: "point before stroke", but let's have a look at the instructions.

Instructions

Steve loves MS Windows calculator in Standard mode. He tries to calculate 2 + 2 * 2 in his favorite programming language. But Steve doesn't know about order of operations and he wonders why answers are different. He expects 8 but gets 6. Help Steve to fix program, so result will be identical to MS Windows calculator.

Solution

So let's come up with the code, I'd say.

function calculate(){
  return (2 + 2) * 2;
}

Very easy indeed, but there are much more difficult Katas (Problems) like calculate with large numbers, use regex, validate stuff etc. pp.

Conclusion

I really like Codewars and if you train constantly it'll really sharpen your skills. Fun and Progress, what do you want more?

Thanks for Reading and a nice Day
