Insert Object To Single Object in Javascript JSON

Question

Good day,

So I'm trying to insert an object to my single javascript json object.

I have this sample result which is called fruits when I enter the value inside console.log(JSON.stringify(fruits))

{"Apple": {"price": 100}, "Banana": {"price": 120}, "Grapefruit": {"price": 300}}

But I need to push or append new fruit which is the Mango in this result.

What I tried so far is something like this.

fruits.push({"Mango": {"price":350})
console.log(fruits)

But apparently, I'm getting an error.

Any help?

Objects do not have a push method. Consider using either the square bracket notation? `fruits["Mango"] = {"price":350}`? — evolutionxbox, Jan 18 '21 at 10:46

Your data is stored in an javascript object as property. To add new property to fruits, try this:

fruits["Mango"] = { price : 350 };

You can use ... spread operator.

fruits = {...fruits, "Mango": {"price":350}}

What do you mean by the top result? – Jan 19 '21 at 03:42

assign() is used to copy objects to a target object

Object.assign(fruits,{"Mango" :{ "price" : 350} });
