Accessing Javascript properties with spcial characters in the key [duplicate]

How do I access a property of an object that is written like this “ex-states”

example:

const product1: {
    'ex-states': 'NY,AK',
    tags: 'freeshipping,shipalone',
    pts: '1=60',
  },

if(product1."ex-states".includes("FL")){
  console.log("test passed")
}
