Options

• keepClassName: Prevent plugin from removing class name (Enabled by default).
• simplify: Enable babel-plugin-minify-simplify: makes the code a lot less readable (Disabled by default).
• undefinedToVoid: Enable 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).
