Lab: Chemical Object Array Fix Sort Revisited Take the page that reads the chemical data in a JSON
file and places it in an array table and add code that will allow the data to be sorted on Melting Points
treating the melting pointing as numbers but always placing the "n/a" entries last whether the user
selects ascending or descending. Furthermore sort the density data similarly -- sort by number (ignoring the
information in parentheses specifying the temperature) and always placing the "n/a" entries last whether
the user choses ascending or descending. Note Radium's density is listed in parentheses; deal with it.
