javascript - When to use requestAnimationFrame? and why we need requestAnimationFrame if we have had css transition? -


i don't know when use requestanimationframe. if requestanimationframe , css both can satisfy needs, 1 should choose?

can show me of applied cases?

thx much~

i think reason opt requestanimationframe on css animations when want quick animations need ensure browsers make smooth. animations jump, stop, pause, return benefit using requestanimationframe.

the thing requestanimationframe uses no cpu power, , draws animation visible user (it doesn't consume if swich tabs, minimize, etc). frames drawn when browser ready , since there no ready frames waiting drawn, there no unnecessary frame draws. so, smoothness guarantee, can safely opt requestanimationframe.

if plan simple doesn't fit above explanation, requestanimationframe overkill , you'd better switch css animations.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
