Typescript Convert Object to Array - because *ngFor does not supports iteration of object

You can use Object.keys(obj) to get named indexes. This will return an array structure which you can use/customize further. A sample use to iterate over object values may look like this

var persons = { 
    john: { age: 23, year:2010},
    jack: { age: 22, year:2011},
    jenny: { age: 21, year:2012}
}

Getting an iterator

var resultArray = Object.keys(persons).map(function(personNamedIndex){
    let person = persons[personNamedIndex];
    // do something with person
    return person;
});

// you have resultArray having iterated objects 

Since Angular 6, there is now a keyvalue pipe operator. Simple do the following:

*ngFor="for item in objectList | keyvalue"

item.key # refers to the keys (134, 135...) in your example
item.value # refers to the object for each key

If you don't need the indexes, you can use Object.values(yourObject) to get an array of the inner objects.
