Class OptimizeReturns
java.lang.Object
com.google.javascript.jscomp.OptimizeReturns
- All Implemented Interfaces:
- CompilerPass
public class OptimizeReturns
- extends Object
- implements CompilerPass
A compiler pass for optimize function return results. Currently this
pass looks for results that are complete unused and rewrite then to be:
"return x()" -->"x(); return"
, but it can easily be
expanded to look for use context to avoid unneed type coersion:
- "return x.toString()" --> "return x"
- "return !!x" --> "return x"
