property value as another property value from the same object

Question

here is my code:

let font = {
  info: {
    height: 5,
    width: 5,
    margin: 1,
  },
  A: [" ### ", "#   #", "#####", "#   #", "#   #"],
  a: [" ### ", "#   #", "#####", "#   #", "#   #"],
  B: ["#### ", "#   #", "#### ", "#   #", "#### "],
  b: ["#### ", "#   #", "#### ", "#   #", "#### "],
  C: [" ####", "#    ", "#    ", "#    ", " ####"],
  c: [" ####", "#    ", "#    ", "#    ", " ####"],
};

I want to set the value of a to A, how do I do that? I've tried a: this.A, a: font.A and a: ( function(){ return this.A } )(), but no one worked

Can you put an attempt to the code too, so we can see where exactly you want to change the value. — Teemu, Jun 28 '21 at 08:09

You can use a getter:

const font = {
  info: {
    height: 5,
    width: 5,
    margin: 1,
  },
  A: [" ### ", "#   #", "#####", "#   #", "#   #"],
  get a() { return this.A; },
  B: ["#### ", "#   #", "#### ", "#   #", "#### "],
  b: ["#### ", "#   #", "#### ", "#   #", "#### "],
  C: [" ####", "#    ", "#    ", "#    ", " ####"],
  c: [" ####", "#    ", "#    ", "#    ", " ####"],
};

console.log(font.a);

@Khalidshammout you can't use arrow functions: [ES6 getter/setter with arrow function](https://stackoverflow.com/questions/33827519) – adiga Jun 28 '21 at 08:18
