That works for the object-specific case from somonek (if he uses
`propertyThree` as his/her variable instead of `myProp`), e.g.:

const myObj = {
    propertyOne: 'someValue',
    propertyTwo: 'another value'
let {propertyThree = myObj.propertyTwo} = myObj;
console.log(propertyThree); // another value
myObj.propertyThree = 'third value';
({propertyThree = myObj.propertyTwo} = myObj);
console.log(propertyThree); // third value

Doesn't help in the general case, but does address this specific case.
