如何在Javascript中计算多维数组中的类似值

如何计算此二维数组中的类似值？请帮忙

var data = [[0,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[1,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[2,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[4,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[3,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[6,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0],[7,0]]

我想要这样的东西

var data3d = [[0,0,1],[1,0,12],[2,0,25]......

我想将计数值保存在第三个空格中，您可以按如下方式使用reduce函数

const reducedArray= data.reduce((accumulator, currentValue) => {
  if(accumulator[currentValue]) accumulator[currentValue][2]++;
  else accumulator[currentValue] = [...currentValue, 1];
  return accumulator;
}, []);

const data3d = Object.values(reducedArray);

你能按照这本指南走吗？
