VisualizaçõesKeys in object include characters that aren't allowed in identifiers
In my code I have this variable:
const operatorPrice = this.state.operatorPrice;
The value of operatorPrice is an object that looks like such:
Now, I want to put those into two separate Tables like such:
4/28/2022
name price category
product1 $20 oil
5/28/2022
name price category
product1 $20 oil
However I am getting this error: 
I guess I understand that the value of this.state.operatorPrice is not an array but I don't know in this format how to access the data and break it up. Any help or documentation would be awesome.

The keys in this object here include characters that aren't valid in normal identifiers. You can't for example access it like this:
operatorPrice.4/28/2022
That's clearly not valid! JavaScript would interpret that key as division with numbers.
Instead you have to use bracket notation to access it:
operatorPrice["4/28/2022"]
Note that unlike using dot notation, any expression can be used within the brackets, so this also does the same as above:
operatorPrice[["4", "28", "2022"].join("/")]
// or even just
operatorPrice[[4, 28, 2022].join("/")]
As @JeffMercado suggests, you should use Object.keys or Object.entries to get the keys (and corresponding entries if required).
const keys = Object.keys(operatorPrice);
keys.forEach((key) => {
operatorPrice[key]; // bracket notation again!
});
