babel-preset-optimizations
Babel preset for optimizations only babel-minify plugins
### Options
- `keepFnName`: Prevent plugin from removing function name (Enabled by default).
- `keepClassName`: Prevent plugin from removing class name (Enabled by default).
- `simplify`: Enable [babel-plugin-minify-simplify](https://www.npmjs.com/package/babel-plugin-minify-simplify): makes the code a lot less readable (Disabled by default).
- `undefinedToVoid`: Enable [babel-plugin-transform-undefined-to-void](https://www.npmjs.com/package/babel-plugin-transform-undefined-to-void): in babel, undefined is considered as unpure, so undefined !== 'string' will not be simplified unless you have this plugin (Disabled by default).
