I'm not sure this kind of feature is available in Javascript. Here is what I wanted to archive.

Let's say we have an object instance called obj and I want to call any function in this object instance but I'm not defining the function name at the beginning.

const obj = {};

obj.functionOne({id: 1}); // execution 1
obj.functionTwo({id: 1}); // execution 2

I wanted to execute one single function (_default) for both execution 1 and execution 2. withing that function I need to know what is the function name actually executed.

eg:

obj = {

  _default: (params) {
    console.log('Function Name is', Function.name); // will be print `functionOne` or `functionTwo`
    console.log(params); // will be print {id: 1} for both cases.
  }

}

Can someone give me some insight on how to archive this kind of requirement?

Thanks in advance.
