Difference between PARSE() and TRY_PARSE() functions

PARSE(), TRY_PARSE() functions are introduced in the SQL Server 2012..
Difference: While attempting to PARSE any column, if you get one or more incorrect values, PARSE function will throw an error. However, if you use TRY_PARSE function, it will not throw error but will return the result as NULL

Ex:

1) SELECT PARSE('249.000' AS INT) AS ParseAsInt

This will return result as 249



2) SELECT PARSE('A249.000' AS INT) AS ParseAsInt  throws ERROR because of invalid data

SELECT TRY_PARSE('A249.000' AS INT) AS ParseAsInt  returns NULL
