If you want to keep both new and existing data from array, better you can store it somewhere in the local variable and iterate over it.

whenever new data comes push new data into existing array, like below -

fullData: Array<any> = [];

this.fullData.push({
      "2018": {
        "score": "0.03726378083229065",
        "TxnNo": "2293760_1-2019r",
        "month_interest_std": "23.632556357702818",
        "m4_last_payment_amount": "1031.94",
        "firstInstalmentDate": "2/28/2018",
        "m6_balance": "15044.57",
        "m2_m1_balance": "0.06796083071380637",
        "period_max": "24.0",
        "paymentmethod_nan": "0"
      })

<div *ngFor='let item of fullData'>{{item?.TxnNo}}</div>
