Get array of objects from array (of strings e.g.)

Question

I need to get array of objects from array of strings. For examaple:

var arr = ["1005", "1005", "1005", "1006", "1006", "1006", "1007", "1007"];
 var result = arr.reduce((iss, index) => {
 iss[index] = (iss[index] || 0) + 1;
 return iss 
}, {});

and the result would be

{1005: 3, 1006: 3, 1007: 2}

So is there a way to get next output:

[{"1005":3},{"1006":3},{"1007":2}]

• Jonas Wilms: Why? There is no advantage of that structure.

Answer 1

If you really want that:

 result = Object.entries(result).map(([key, value]) => ({[key]: value}));

Answer 2

You can extend result by iterating its keys

result = Object.keys ( result ).map( s => ({ [s] : result[s] }) );
