5.9 W RITING E FFICIENT S CRIPTS
Good programming practices should be used when developing scripts for
CETerm. In general, it is important to conserve memory, minimize script
compilations, and limit execution times. Please refer to a JavaScript
programming book for more information.
We recommend “JavaScript: The
Definitive Guide (5th Edition)
” by David Flanagan. The following URL is an
excellent starting point for in-depth details about JavaScript and good
programming practices:

5.9.1 Use Local Variables
Whenever possible, use local variables within functions and declare them with
the var keyword, like this:
var status;
var message = "hello";
var i, j, k;
If you fail to use the var keyword, then JavaScript automatically creates a global
variable with that name if it has not already been declared outside a function.
