Hello I have the below json in ionic application
Update
I change it to get an array from api and I get the following

```
{
"chest": {
    "chest": {
        "1": [
            "1",
            "2"
        ],
        "3": [
            "1",
            "2",
            "3"
        ]
    },
    "hints": {
        "1": [
            "test1"
        ],
        "3": [
            "test2"
        ]
    }
},

```

How can I use to display the key and the value
I try the below 

```
  <ion-item *ngFor="let chest of workout.data.chest;let i=index" (click)="openNew(new.id)" detail-push >

<b> {{ chest}} </b> <br>

```

```
  <span *ngFor="let exercise of chest.chest |keys ">   
  <span *ngFor="let hints of chest.hints |keys ">        
  Machine: {{exercise.key}}, Days: {{exercise.value}}  
, Hints: {{hints.value}} <br>

```

I try above but I get in wrong place the hint and I get duplicate records
