Week 27: December 1-5 JavaScript 4

Hi!

  Well, we just continued typing and busy making flow charts.

Here are some examples of JavaScript 4...

  Looping Statements

     Looping statements are used to run the same block of code a specified number of times.

In VBScript we have four looping statements:

• For...Next statement - runs code a specified number of times
• For Each...Next statement - runs code for each item in a collection or each element of an array
• Do...Loop statement - loops while or until a condition is true
• While...Wend statement - Do not use it - use the Do...Loop statement instead

    The Nested Loops operator performs the inner join, left outer join, left semi join, and left anti semi join logical operations.

Nested loops joins perform a search on the inner table for each row of the outer table, typically using an index. Microsoft SQL Server decides, based on anticipated costs, whether to sort the outer input in order to improve locality of the searches on the index over the inner input.

Any rows that satisfy the (optional) predicate in the Argument column are returned as applicable, based on the logical operation being performed.

Nested Loops is a physical operator.
