It's true that for most little kids, typing is painfully slow, but they get faster very quickly. And typing is an important skill these days, so it's not a terrible thing to give them lots of practice. Bonus: we've observed that kids actually enjoy learning to type. It's a distinctly grown-up activity, and that's awesome.

That said, to speed things up, Bitsbox uses short commands. Consider these two lines of code:

window.document.getElementById('app-canvas').style.background = 'rgba(255,0,0,1)';

vs.

fill('red')

They both do the same thing. The second line is the Bitsbox way. Which would you rather explain to a seven-year-old?
