Concatenate strings into an array in javascript

Question

I have these array in javascript that is going to be the input data for a graph using highcharts

data = [20, 29, 25, 30, 21, 17, 20, 19, 18];

and what I need is to be able to concatenate certain strings to get in the end these

data = [{ color: '#55B647', y: 20 }, 29, 25, 30, 21, 17, 20, { color: '#F15B49', y: 19 }, 18];

I was trying to acces the array and assing the new value like these

data[0]= "{ color: '#55B647', y:" + data[0] + "}";

But is not working, how can I do it? What's wrong with my code?

Answer 1

This should be right:

data[0] = { color: '#55B647', y: data[0] };

Rememeber that an object in JS is declared like:

var object = { key1: value1, key2: value2};
