Here is what I have: 

```
fields = [ { apple: 'red' }, { banana: 'yellow' } ]

fields.forEach(field => {
    // trying to get the key here
    if (Object.keys(field)[0] === 'apple')
        console.log('works!')
})

```

I want to ask is there a simple way for me to get the key? I feel I was making it too complicated by using 

```
Object.key(field)[0]

```

add: I am just trying to get each key from this array of object and compare with a string.
