Obtain the name of the object method from inside the method itself

Imagine having an object like this:

var app = {}

inside which there is a method:

app = {
   initialize: function () {
   }
}

Is it possible to retrieve the name of the method 'initialize' from within the initialize() function without explicitly searching for 'initialize'? This is in the scenario where the method name can vary and cannot be assumed beforehand.

app = {
   initialize: function () {
      // access method name 'initialize' here
   }
}
app.initialize();

I attempted using callee but it only returns an empty string

Answer №1

To implement a named function expression, consider the following example:

const application = {
  initialize: function start() {
    console.log(arguments.callee.name);
  }
};

application.initialize();  // => "start"

It's important to note that strict mode prohibits the use of arguments.callee.

In your scenario, you are assigning an anonymous function expression to the initialize property of your object. To provide the function with a name, you should opt for a named function expression instead.
