Spread operator
const obj1 = { foo: 'pikachu' } const obj2 = { bar: 'charizard' } const result = { ...obj1, ...obj2 }
Object.assign with separate target
const obj1 = { foo: 'pikachu' } const obj2 = { bar: 'charizard' } const result = Object.assign({}, obj1, obj2)
Object.assign with first object as target
const obj1 = { foo: 'pikachu' } const obj2 = { bar: 'charizard' } const result = Object.assign(obj1, obj2)
