JavaScript is not statically typed.
JavaScript does not have unions.
JavaScript does not have structs.

You can only create an object.

const AZ = {
  A: 0,
  B: ""
}
AZ.A = 123;
AZ.B = "one two three";

or make a function

function makeAZ(A, B) {
  return {
    A: A,
    B: B
  }
}
const AZ = makeAZ(123, "one two three");

or make a class and then instantiate instances.
