how to access the dynamic object in angular

Question

My Code:

export class AppComponent implements OnInit {
 public manipulate: any ;
 ...
 this.results.forEach(result => {
   var index = result.date_value;
   if (!this.manipulate.hasOwnProperty(index)) {
     this.manipulate.{index} = [];
   }
   this.manupulate.{index}.push(result);
 });
}

Expected Result:

this.manupulate = {
  20171001 : [
     0: { resultset },
     ...
  ]
}

How to write the program. If I use Array the browser handed. the reason is a high range of the index value.

The below javascript code is run perfectly.

manupulate[20171001] = 
  [
     0: { resultset },
     ...
  ]
}

If I use typescript the browser handed.

this.manupulate[20171001] = 
  [
     0: { resultset },
     ...
  ]
}

Thanks for all.

try this : this.manupulate[index].push(result);

Try this :

use this.manupulate[index].push(result); instead of this.manupulate.{index}.push(result);

if (!this.manipulate.hasOwnProperty(index)) {
    this.manipulate[index] = [];
}
this.manupulate[index].push(result);

I tried but the system is handed due to index value is large input. Ex: 20171003 this is large value it's hand the browser. Please try below code: this.manupulate[20171003]=10;

@BalasubramaniSamiyappan Are you initializing your object? public manipulate: any = {}

My Initialization mistake: public manipulate: any = [] this is wrong.
