Killing Two Birds with One Stone

I’m challenging to learn SproutCore never using Japanese reference. To make web applications is not my prima’s work. So the challenge is free of care. Even if I can’t master it, I will not become defects. Fortunately, if I can master it, it will be an excellent result. I think that to read only English reference is also practice. This method is killing two birds with one stone. However I guess it’s arduous time until I find my feet. But To learn a new development environment is delightful. So this rule is my challenge.
