The code posted above is working properly on Firefox and Chrome but I get an error in Internet Explorer. Error message:
Object doesn't support property or method 'find'
Answer
Here is a work around. You can use filter instead of find; but filter returns an array of matching objects. find only returns the first match inside an array. So, why not use filter as following;
data.filter(function (x) {
return x.Id === e
})[0];
