I will be down voted for saying so, but "than" and "then" seem to be reversed throughout the entire article. I would like to learn more about promises now.
You're absolutely right! My English is far from being perfect and in addition I was rushing to get this post out making bunch of mistakes. I tried to fix all the "than" "then" issues, thanks for pointing that out ;)
I was thinking about promises, because I just wrote a procedurally generated universe in Javascript with over 2^100 locations. To do the procedural generation correctly, the Math.random() function has to be called in the same order every time for generating each "sector." I had used promises in Smalltalk, but never found an application super for them and was thinking that promises would be a way to code this cleanly.
