Tests:

Basic object spread
const obj = { foo: 1, bar: 2 }; const finalObject = { baz: 3, ...obj };
Basic assign operator
const obj = { foo: 1, bar: 2 }; const finalObject = Object.assign({baz: 3}, obj);
Assign with empty object
const obj = { foo: 1, bar: 2 }; Object.assign({}, obj, { baz: 3 });
Spread operator with two existing objects
const obj = { foo: 1, bar: 2 }; const obj2 = { baz: 3 }; const finalObject = {...obj2, ...obj };
Object assign with two existing objects
const obj = { foo: 1, bar: 2 }; const obj2 = { baz: 3 }; const finalObject = Object.assign(obj2, obj );
