>>This should be an easy question. I have two datetime strings like "02/05/2018 12:00" and "02/18/2018 14:41". I want to compare date portions of these strings to find if they are the same or different.

I used this code which seems to work:

let newDate = new Date(new Date(val).toDateString());
                                let originalDate = new Date(new Date(modelValue).toDateString());
                                if (newDate.valueOf() !== originalDate.valueOf()) {
