A few more noteworthy ones: Variable name reuse: var x = .....; print(x); var y = ......; print(y) becomes var x = .....; print(x); x = ......; print(x)
More aggressive inlining with variables and functions. A lot more small optimizations that saves a char here and there. Closure Compiler would also put more effort into your JSNI code for obvious reasons. -Alan On Thu, Jul 5, 2012 at 9:31 AM, Thomas Broyer <t.bro...@gmail.com> wrote: > > > On Thursday, July 5, 2012 5:37:08 AM UTC+2, Magno Machado wrote: >> >> I was impressed to see the results achieved on gwt 2.5 by combining the >> gwt compiler and closure compiler. >> >> Well, I always thought there's nothing that closure could do that the gwt >> compiler couldn't already do, because gwtc have a lot more information >> about the source than closure compiler. >> > > Yes and no: Closure has "static typing" via JSDoc annotations, and uses > the same kind of monolithic compilation (i.e. I know everything about what > will run, so I know what is never used that I can remove). > > So I wonder what kind of optimizations closure is doing that were not >> already done by the gwt compiler? >> > > One small optimization I've read on the Closure Compiler group that I know > GWT doesn't do: ["ab", "cd", "ef", "ghij"] is compiled into > "ab,cd,ef,ghij".split(",") ! > (it's more in terms of perfs than in code size I guess though). > I don't know about the other differences. > > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To view this discussion on the web visit > https://groups.google.com/d/msg/google-web-toolkit/-/EBpT-fnjCHcJ. > > To post to this group, send email to google-web-toolkit@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
