在lodash中，如何深层清除？

Question

I have a data structure as such at the bottom.. and I need to remove from the array the totype.id === 'REG' and also all instances of the object property budgt .

I have accomplished part of this using the following code, and was going to do another iteration to remove the budgt from all remaining totype s but that didn't seem the best way to do it.

_.each(data, function (d, i) { // iterate over each "org"
  _.each(d.occs, function (occ) { // iterate over each "occ" in current "org"
    return _.remove(occ.totypes, function (totype) { // remove the totype REG from "totypes"
      return totype.id === 'REG'
    })

    // how do i remove the "budgt" from each remaining totype
  })
})

sample data

var data = [
  {
    org: "org1",
    occs: [
      {
        name: "occ1",
        totypes: [
          {
            id: "REG",
            act: 1,
            auth: 2,
            budgt: 3
          },
          {
            id: "PRV",
            act: 1,
            auth: 2,
            budgt: 3
          }
        ]
      },
      {
        name: "occ2",
        totypes: [
          {
            id: "REG",
            act: 1,
            auth: 2,
            budgt: 3
          },
          {
            id: "PRV",
            act: 1,
            auth: 2,
            budgt: 3
          }
        ]
      },
  },
  {
    org: "org2",
    occs: [
      {
        name: "occ1",
        totypes: [
          {
            id: "REG",
            act: 1,
            auth: 2,
            budgt: 3
          },
          {
            id: "PRV",
            act: 1,
            auth: 2,
            budgt: 3
          }
        ]
      },
      {
        name: "occ2",
        totypes: [
          {
            id: "REG",
            act: 1,
            auth: 2,
            budgt: 3
          },
          {
            id: "PRV",
            act: 1,
            auth: 2,
            budgt: 3
          }
        ]
      }
    ]
  }
]

There is no way to "deep remove" the way you are describing with Lodash. It doesn't provide any querying construct like MongoDB.
