js - How to change one key's value based on another key's value in array of objects

Question

I have an array of objects like this:

var chartData = [{count: 0, idTag: \"24\"}
                 {count: 0, idTag: \"25\"}
                 {count: 0, idTag: \"         


        

Answer 1

var chartData = {24: 0,
                 25: 0,
                 26: 0};

And then the loop becomes

for (i=0; i
