Also known as aliasing, this feature has been deprecated in the Closure Compiler since its - * initial release, where it is unavailable from the CLI. The Closure Compiler allows one to log and - * influence this process. In contrast, this implementation does not introduce - * any variable declarations in global code and derives String values from - * identifier names used as property accessors.

- *

Consolidating literals may worsen the data compression ratio when an encoding - * transformation is applied. For instance, jQuery 1.7.1 takes 248235 bytes. - * Building it with - * UglifyJS v1.2.5 results in 93647 bytes (37.73% of the original) which are - * then compressed to 33154 bytes (13.36% of the original) using gzip(1). Building it with the same - * version of UglifyJS 1.2.5 patched with the implementation of consolidation - * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison - * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes - * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned - * 33154 bytes).

- *

Written in the strict variant - * of ECMA-262 5.1 Edition. Encoded in UTF-8. Follows Revision 2.28 of the Google JavaScript Style Guide (except for the - * discouraged use of the {@code function} tag and the {@code namespace} tag). - * 100% typed for the Closure Compiler Version 1741.
