     let arrayOutput = [];
                myArray?.map((c) => {
                    (!(arrayOutput.indexOf(c) > -1)) ? arrayOutput.push(c) : null;                
                });

One Liner

var arrOutput = Array.from(new Set([1,2,3,4,5,5,6,7,8,9,6,7]));
alert(arrOutput);

I modified the code with remove duplicate value based on productTitle.

 success: function(data){
             var array = [],
             Finalresult = [];

           $.each(data, function (index, value) {
               if ($.inArray(value.productTitle, array) == -1) {
                array.push(value.productTitle);
                Finalresult.push(value);
              }
           });
         for (var i = 0; i < Finalresult.length; i++) {
                        $(".suggesstions").append("<ul>"+Finalresult[i]["category"]+" "+Finalresult[i]["productTitle"]+"</ul>");
                     }
        console.log(Finalresult);

    }

First, you have to remove all duplicate entries from array , like this

 var myArr = [2, 5, 5, 7, 7, 8, 9, 9, 9, 1, 3, 3, 4, 5];
 var newArr = $.unique(myArr.sort()).sort();

for (var i = 0; i < newArr.length; i++) {
         //your code
}
