如何使用Lodash将对象替换或附加到另一个对象

Question

I have 2 objects

{
    "Simon": { 
        "occupation": "garbage man",
        "age": "21"
    }
}

and this one

{
    "wife": "Kate"
}

How will I insert the second object to the first object to result as

{
    "Simon": { 
        "occupation": "garbage man",
        "age": "21",
        "wife": "Kate"
    }
}

And also can be applied even when wife exists:

{
    "wife": "Shandia"
}

Results to

{
    "Simon": { 
        "occupation": "garbage man",
        "age": "21",
        "wife": "Shandia"
    }
}

Is there a way to achieve this using lodash?

Answer 1

You don't need lodash for it. Use Object.assign to do that in plain JS. It works for the second case as well.

And if you really want to do it with lodash, use _.assign ; it works the same.

 var simon = { "Simon": { "occupation": "garbage man", "age": "21" } } var wife = { "wife": "Shandia" }; Object.assign(simon.Simon, wife); console.log(simon); 

Answer 2

As alternative, if you prefer to not change the original object (immutable way), you can use ES6 spread operator.

 var simon = { "Simon": { "occupation": "garbage man", "age": "21" } } var wife = { "wife": "Shandia" }; const simonWithWife = { Simon: { ...simon.Simon, ...wife } } console.log(simon); // doesn't get changed console.log(simonWithWife);
