How can I filter an array of objects between two dates?

Aside from the occasional jQuery selectors and element modifications, I'm not too great at javascript. For a problem I'm having, I need to filter out a javascript object by date. I have a structure that looks like this:

Object { version: 3.1.1, released_on: 2016-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 }

I want to find all of the objects from 10 years so between 2016-08-21T00:00:00.000Z and 2010-08-21T00:00:00.000Z The problem I'm experiencing is that the released_on: field is a string not a date. Would I need to create a new Date() object convert it into a string, and then use .filter or would I do the opposite, convert the string into a date and then filter. Has anyone tried something like this before?

You might do as follows;

var data = [{ version: 3.1.1, released_on: 2016-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2011-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2009-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2006-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2013-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2017-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

            { version: 3.1.1, released_on: 2015-08-21T00:00:00.000Z, high_vulns: 15, medium_vulns: 10, low_vulns: 5 },

           ],

      ed = new Date(2016-08-21T00:00:00.000Z).getTime(),

      sd = new Date(2010-08-21T00:00:00.000Z).getTime(),

  result = data.filter(d => {var time = new Date(d.released_on).getTime();

                             return (sd < time && time < ed);

                            });

console.log(result);
