如何删除数组中的重复对象并使用JavaScript计算重复的事件？

我有这个数组：

var arr = [{
  "gid": "affected_bxu_nrt.1",
  "bldg_name": "Unknown",
  "psa_brgy": "Bading Pob. (Bgy. 22)",
  "bldg_type": "Residential",
  "hazard_level": "HIGH"
}, {
  "gid": "affected_bxu_nrt.2",
  "bldg_name": "Unknown",
  "psa_brgy": "Bading Pob. (Bgy. 22)",
  "bldg_type": "Residential",
  "hazard_level": "HIGH"
}, {
  "gid": "affected_bxu_nrt.3",
  "bldg_name": "Unknown",
  "psa_brgy": "Bading Pob. (Bgy. 22)",
  "bldg_type": "Residential",
  "hazard_level": "HIGH"
}, 
...

我已设法删除重复的对象，但如何计算重复项的出现次数？

这个想法是，如果数组中的对象是相同的，请计算它。输出应该为每个对象添加count属性，并且count属性的值应该是它的出现。

const result = {
  data: arr
}

result.data = result.data.filter((result, index, self) =>
  index === self.findIndex((t) => (t.bldg_name === result.bldg_name && t.psa_brgy === result.psa_brgy && t.bldg_type === result.bldg_type && t.hazard_level === result.hazard_level)

  )
)
console.log(result)
