One possible approach is to employ the reduce function in the following manner
const reducedArray= data.reduce((accumulator, currentValue) => {
if(accumulator[currentValue]) accumulator[currentValue][2]++;
else accumulator[currentValue] = [...currentValue, 1];
return accumulator;
}, {});
const data3d = Object.values(reducedArray);
