Javascript Loop over array of objects and get unique values

Question

I have an array of car objects (carArray) and I want to loop over that array and fill a new array with the unique objects with only the type of CarA: 'Ford'.

const carArray = [
{carA:'Ford'},
{carA:'Ford'},
{carB:'GM'},
{carB:'GM'},
{carA:'Ford'},
{carA:'Ford'},
{carB:'GM'},
{carB:'Ford'},
]

Can someone tell me how I can do this?

Thank you so much for your time. regards, L

Try this

 let  newArray = [];
 carArray.forEach(function(car) {
   let arrayKey = Object.keys(car)[0]
   if (newArray.length > 0) {
       newArray.find(function (data) {
         if(!data.hasOwnProperty(Object.keys(data)[0])) { 
            newArray.push(car);
         }
       })
    }  else newArray.push(car)
 });
