What are babel-plugin-transform-es2015-function-name's main functionalities?

Assigning names to anonymous functions

This feature automatically assigns a name to an anonymous function based on the variable it is assigned to. This makes debugging easier by providing more informative stack traces.

const myFunc = function() {}; // Transformed to: const myFunc = function myFunc() {};

Assigning names to object methods

This feature assigns names to anonymous functions that are used as object methods. This helps in identifying the method in stack traces.

const obj = { method: function() {} }; // Transformed to: const obj = { method: function method() {} };

Assigning names to class methods

This feature ensures that class methods have names, which can be useful for debugging and stack traces.

class MyClass { myMethod() {} } // Transformed to: class MyClass { myMethod() {} }
