Question about Javascript: Can I assign two names to the same member? [closed]

Question

I have a set of objects, that contain references to other objects. There is always a general reference: nextObject. But sometimes, I know more about the object beside me. So I could use a member like: theNextSentenceInThisParagraph.

Some code, that knows what they are dealing with, could use tNSITP. Other code, that doesn't know about the adjacent object, would use nO. I could assign two members, each with its own name, pointing to the adjacent object. But I'd rather assign two names to the same member. Is that possible?

myObject
    nextObject: theNextSentenceInThisParagraph: reference-to-next-object

Sure, but not with the syntax you're proposing. What you're looking for is get and/or set:

const obj = {
  foo: 0,
  get bar() {
    return this.foo;
  },
  set bar(value) {
    this.foo = value;
  },
};

console.log('foo', obj.foo);
console.log('bar', obj.bar);

obj.foo = 1;

console.log('foo', obj.foo);
console.log('bar', obj.bar);

obj.bar = 2;

console.log('foo', obj.foo);
console.log('bar', obj.bar);
