Create a react native application with Expo and Shadow-CLJS!

/**
 * Edge 16 & 17 do not infer function.name from variable assignment.
 * All other `function.name` behavior works fine, so we can skip most of @babel/transform-function-name.
 * @see https://kangax.github.io/compat-table/es6/#test-function_name_property_variables_(function)
 *
 * Note: contrary to various Github issues, Edge 16+ *does* correctly infer the name of Arrow Functions.
 * The variable declarator name inference issue only affects function expressions, so that's all we fix here.
 *
 * A Note on Minification: Terser undoes this transform *by default* unless `keep_fnames` is set to true.
 * There is by design - if Function.name is critical to your application, you must configure
 * your minifier to preserve function names.
