/** |
|
* 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. |
