I am trying to store cake prices in an object for different sizes for example:
1.5kg = $10 
2kg = $12 
2.5kg = $15 
3kg = $20 
like
let cakePrices = {
   "1.5kg" : "$10",
   "2kg" : "$12",
   "2.5kg" : "$15",
   "3kg" : "$20"
}
I know this goes against variable naming convention since a variable name can't start with a number nor can it have a period(.)  
So in what way can I store and retrieve these values?
