They are equal to each other. There is absolutely no difference between them. They are equal in performance as well as implementation. JOIN is actually shorter version of INNER JOIN.

Example :

An INNER JOIN will retrieve all records from both tables that have matching values for whatever column you're joining them on. Records from either table that don't match will not be retrieved. A LEFT JOIN will retrieve all records from the left (first) table, and only the records from the second table with matching values for the joining column, filling in any empty spaces with NULL values
