How to loop JSON data to get printed values of percentages for all objects using for each or other

Question

How to iterate through an array of JSON data. Can you help with the code:

var percent=(100 * this.contributed) / this.max;
percent= Math.floor(percent);

This is the logic. I need to apply this for all objects using for each

var dashboardval= [
    {"contributed": 20, "max": 35 },
    {"contributed": 22, "max": 35},
    {'contributed': 35, "max": 35,},
    {"contributed": 32, "max": 35}
   ];

I need percentage value for every object ..not single object — sagar kn, Oct 20 '18 at 20:48

Using ES6 you can do this by reducing the array of objects:

var objects = [{"contributed": 20, "max": 35}, {"contributed": 22, "max": 35}, {'contributed': 35, "max": 35}, {"contributed": 32, "max": 35}];

var percent = objects.reduce((acc, {contributed, max}) => ~~((100 * contributed) / max));

console.log(percent);
