How to calculate sum of object keys in array - javascript

Question

Question

I am working with firebase and react native.

I have returned an array from my firebase database that looks like this.

[Object, Object,         


        

Answer 1

Have you tried accessing the object in the array and calling the property?

var array = [object, object, object];
var sum = array[0].level + array[1].level + array[2].level;
