Notes

\* JavaScript was originally designed for small DOM operations. Now that we’re building large-scale apps in JS, we can use some help. \* Google uses Closure for all but a couple products \* The Closure compiler can perform ~55 optimization passes, including linting code, validating function definitions, performing gzip-optimized compression, trimming dead branches \* Closure can also provide compile-time constants, e.g., “if(INTERNAL){…”, and trim unused branches that result \* Closure uses a graph coloring heuristic for variable renaming
