Modifying Javascript Code to Add Days to Date Entered

Hello! I'm a complete newbie to JavaScript coding, and I need a little help modifying a code I have to serve a slightly different purpose. The code below uses the date entered for the question, adds 10 days, and then sets the new date as embedded data. (A friend helped me with this part!) I need to use the same date and add 5 days to create a different embedded data point. I reviewed several other discussions and tried modifying the code on my own, but instead of adding 5 days to the answer entered, it added 5 days to the original calculation (answer entered + 10). So . . . how would I modify this to get it to calculate Date + 10 AND Date + 5 separately (and set both as different embedded data)? (I'm also OK with setting up the Date + 5 as part of another question, just pulling the answer from the previous question . . . but I wasn't sure exactly what to change to make that work.) Thanks in advance for your help!

Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
jQuery(".InputText:eq(0)").on("change", function(){
var theDate = new Date(jQuery(".InputText:eq(0)").val())
   var futureDateRaw = new Date(theDate.setDate(theDate.getDate() + 10));
console.log(futureDateRaw)
   var futureDate = (futureDateRaw.getMonth() + 1) + '/' + futureDateRaw.getDate() + '/' + futureDateRaw.getFullYear()

  Qualtrics.SurveyEngine.setEmbeddedData("DatePlus10", futureDate);
})

});

Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
