spread operator to merge / mixin objects

spread.js

const a = {
  a: {
    b: {
      c: 4,
      d: 'str'
    }
  }
};

const b  = {a: {b: {c: 5}}};

console.log({...a,...b});  // { a: { b: { c: 5 } } }

// now reverse the arguments

console.log({...b,...a});  // { a: { b: { c: 4, d: 'str' } } }

Oooh I see, thank you for clearing that up! I think I was ignoring the values xD
