To find the top earning employee in a SQL table, you can use a SQL query with the MAX function on the salary column.
Use a SQL query with the MAX function on the salary column to retrieve the highest salary in the table.
Join the result with the employee table to get the details of the top earning employee.
Example: SELECT * FROM employees WHERE salary = (SELECT MAX(salary) FROM employees);
Generators produce values one at a time, while iterators are objects that allow iteration over a sequence of values.
Generators are functions that can pause and resume execution, producing a sequence of values lazily.
Iterators are objects that implement the Iterator protocol, allowing iteration over a sequence of values.
Generators can be created using function* syntax in JavaScript, while iterators can be created u...
