I have two objects. First object old object. Second object new object. As a result I want to combine these objects. How do I go the easy way. Example:
// old object
{
name: 'exapmle name',
surname: 'example surname',
number: '123456'
}
// new object
{
name: 'change name',
surname: 'change surname',
number: null
}
// result
{
name: 'change name',
surname: 'change surname',
number: '123456'
}
I think spread syntax can help for this purpose.
const old = { name: 'exapmle name', surname: 'example surname', number: '123456' };
const newObj = { name: 'change name', surname: 'change surname', };
const result = { ...old, ...newObj };
console.log(result);You can use Object.assign as so:
oldObj = {
name: 'exapmle name',
surname: 'example surname',
number: '123456'
}
newObj = {
name: 'change name',
surname: 'change surname',
}
result = Object.assign({}, newObj, oldObj)
result => {name: "exapmle name", surname: "example surname", number: "123456"}
