Mumbled Ramblings and nothingness

 We have a combox who's values are numerical. If we select a value, then another combobox should generate the values based on it.  But, the second combox is getting dynamic values from a file (which is dependent on the user and can be changed).  When it comes to static, use sub-string for that splitting up the value and using "==" to match it with the number. But when it comes to dynamic, it's better to use index and streams to fetch the values. https://stackoverflow.com/questions/41134142/filtering-strings-from-an-array

We have finally done with JSON and switched out database to Firebase which loads our image on the web pages without disappearing in any way.
