A closure is an inner function that has access to the variables in the outer (enclosing) function’s scope chain. The closure has access to variables in three scopes; specifically: (1) variable in its own scope, (2) variables in the enclosing function’s scope, and (3) global variables.

Here is a simple example:

var globalVar = "xyz";

(function outerFunc(outerArg) {
  var outerVar = 'a';

  (function innerFunc(innerArg) {

## mysql join

    INNER JOIN OR Equi join: Returns all rows when there is at least one match in BOTH tables
    LEFT JOIN: Return all rows from the left table, and the matched rows from the right table
    RIGHT JOIN: Return all rows from the right table, and the matched rows from the left table
    FULL JOIN: Return all rows when there is a match in ONE of the tables
    Self join:You use self join when you want to combine rows with other rows in the same table. To perform the self join operation, you must use a table alias to help MySQL distinguish the left table from the right table of the same table.
    SELECT  a.ID, b.NAME, a.SALARY
     FROM CUSTOMERS a, CUSTOMERS b
     WHERE a.SALARY < b.SALARY;
