Tests:

  • Basic object spread

    AخA
     
    const obj = { foo: 1, bar: 2 };
    const obj2 = { baz: 3 };
    const finalObject = ({...obj2, ...obj })

  • Basic assign operator

     
    const obj = { foo: 1, bar: 2 };
    const obj2 = { baz: 3 };
    const finalObject = Object.assign(obj2, obj);

  • Assign with empty object

     
    const obj = { foo: 1, bar: 2 };
    const obj2 = { baz: 3 };
    Object.assign({}, obj, obj2);
