I want do declare a variable inside an object using a function that is being declared in that same object. But when I try I get an error:
const obj = {
  alpha: 4,
  
  somestuff: function()
  {
    return 120;
  },
  
  // Does not work
  beta: this.somestuff()
  // Does not work
};
// Works
obj.beta = obj.somestuff();
console.log(obj.beta);
// WorksHow can I make it work when object is being declared, not after it was declared
