Learning how to make JSON....

So the key piece of code is JSON.stringify

This example shows it very simply:

var a = [];

a.push({ name: 'x1' });

a.push({ name: 'x2' });

console.log(JSON.stringify(a));

In the console log you get:

[{"name":"x1"},{"name":"x2"}] 

from a comment on this page:
http://freshbrewedcode.com/jimcowart/2013/01/29/what-you-might-not-know-about-json-stringify/

So testing this:

      var start = 21;

      var a = [];

      a.push({ name: start });

      a.push({ name: 'x2' });

      console.log(JSON.stringify(a));   

In the console log you get:

     [{"name":21},{"name":"x2"}] 

GOOD!!!!

VERY STRANGELY, EVEN WHEN I SEND IT AS JSON, THE SCRIPT I HAVE WRITTEN DOESN'T SEEM TO LIKE IT. 

I DON'T KNOW QUITE WHY!

Surprisingly, a variation on push seems to work:

           var start = 21;

           var end = 193;

           var color = "blue";

           

           var a =[];

           a.push({ 'start': start, 'end': end, 'color': color });

This gives data that the molecule renderer seems to like.
