I made a similar question not too long ago, but I have another twist to it. Suppose I have this:

  var config = {
    a: {
        value: '',
        get getValue(): {
            return this.valueType
        }
    },
    b: {
        value: '',
        get getValue(): {
            return this.value
        }
    },
    c: {
        value: {
          d: '',
          e: '',
          f: ''
        },
        get getValue(): {
            return this.d + " " + this.e + " " + this.f
        }
    }
  }

Then, I am doing this:

  assignConfig(conf) {
    array.push({
      value: { ...config[conf] } //conf Could be a, b, c
    }
  }

The idea is that I can call getValue and get the data in that format, but I will be calling it from the array where I'm pushing the config. The values inside valueType will be changing, since they are being used in an ngModel. When I try this, getValue is always empty. Is this possible to do? Maybe there's another way to approach this.
