Re: gwtc X closure optimizations
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.

gwtc X closure optimizations
