babel-plugin-transform-object-spread-inline

A Babel plugin that transpiles object spread syntax into inline assignments and for loops using Object.keys, avoiding the slower for...in with hasOwnProperty check. Version 0.0.3 appears to be the latest, with no recent updates. It provides a performance alternative to the default babel-plugin-transform-object-rest-spread by generating faster code for object spreads, especially when only one spread is used. Note that it does not handle object rest syntax and may not be suitable for multiple spreads per object.
