如何推入数组并使用 Id 作为 object 的索引

Question

This is the result I want to achieve

    11:{amount:736
    wrk_pay_id:11},

    10:{amount:714.29
    wrk_pay_id:10},

    14:{amount:500
    wrk_pay_id:14},

    13:{amount:857.14
    wrk_pay_id:13},
   
    20:{amount:777
    wrk_pay_id:20}

this the result of DeductionArray.. I want to change 0,1,2,3,4 indexes to 11,10,14,13,20

 0:{amount:736
    wrk_pay_id:11},

    1:{amount:714.29
    wrk_pay_id:10},

    2:{amount:500
    wrk_pay_id:14},

    3:{amount:857.14
    wrk_pay_id:13},
   
    4:{amount:777
    wrk_pay_id:20}

This how I push it on my DeductionArray.. this.generated salary Have 4 object and the deduction is on nested array so that I use 2 foreach to get the value in deduction

const arr = Object.entries(this.generated_salary)
arr.forEach(([key, value]) => {
  Object.entries(value.deduction).forEach(([acc, item]) => {
    this.DeductionArray.push({
      amount: item.amount,
      wrk_pay_id: item.wrk_pay_id
    })

This.generated_salay

[
  {
    "f_name": "Cy",
    "deduction": {
      "11": {
        "amount": 736,
        "wrk_pay_id": 11
      }
    }
  },
  {
    "f_name": "Hel",
    "deduction": {
      "10": {
        "amount": 714.29,
        "wrk_pay_id": 10
      },
      "14": {
        "amount": 500,
        "wrk_pay_id": 14
      }
    }
  },
  {
    "f_name": "edd",
    "deduction": {
      "13": {
        "amount": 857.14,
        "wrk_pay_id": 13
      }
    }
  },
  {
    "f_name": "JAY",
    "deduction": {
      "20": {
        "amount": 777,
        "wrk_pay_id": 20
      }
    }
  }
]

I'm still guessing due to your question formatting but it looks like you really just want to combine the various deduction objects into a single object. I don't think an array is a good choice if you're relying on the indexes as keys.

 // ignore this line, this is just your existing data minified for the demo const generated_salary = [{"f_name":"Cy","deduction":{"11":{"amount":736,"wrk_pay_id":11}}},{"f_name":"Hel","deduction":{"10":{"amount":714.29,"wrk_pay_id":10},"14":{"amount":500,"wrk_pay_id":14}}},{"f_name":"edd","deduction":{"13":{"amount":857.14,"wrk_pay_id":13}}},{"f_name":"JAY","deduction":{"20":{"amount":777,"wrk_pay_id":20}}}] const deductions = generated_salary.reduce((c, { deduction }) => ({...c, ...deduction }), {}) console.info("deductions =", deductions)

 .as-console-wrapper { max-height: 100%;important; }

This builds a new object by iterating each entry in generated_salary and collecting each deduction object by merging it into the collection as it finds them.
