Push varaibles into an array with containing variables - Javascript

Question

I have a code

var myArray = []

myArray.push( { "bob" : { "banana" : "yellow" } })

console.log(myArray)

which returns

{
    "bob": {
        "banana": "yellow"
    }
}

Now, I want to change the variables like this:

var myArray = []

var name = "bob"
var fruit = "banana"
var fruitcolor = "yellow"

myArray.push( { name : { fruit : fruitcolor } })

console.log(myArray)

but it doesn't return the same result. How do I fix this?

Thanks!

myArray.push( { [name] : { [fruit] : fruitcolor } }). Use bracket notation. — Hassan Imam

If you want to set a string as a key of an object you have to use bracket notation

Replace

myArray.push( { name : { fruit : fruitcolor } })

with :

myArray.push( { [name] : { [fruit] : fruitcolor } })
