4. DYNAMIC LANGUAGE RUN TIME
• A dynamic type system, to be
sheared by all language using the
DLR services.
• Dynamic method dispatch.
• Dynamic code generated.
• Hosting API.
The dynamic
language run time
(DLR) form
Microsoft runs no
top of the
common
language runtime
and provides
computer
language services
for several
different
language. These
services include:

5.  A dynamic programming language is a
programming language in which operations
otherwise done at compile time can be done at run
time . For example, JavaScript it is possible to
change the type of a variable or add new properties
or methods to an object while the program is
running.
 This is opposed to so-called static programming
language , in which such changes are normally not
possible.

13. DYNAMIC LANGUAGE PROVIDE THE FOLLOWING
ADVANTAGES FOR DEVELOPERS:
 The ability to use a rapid feedback loop. This lets
you enter several statement and immediately
execute them to see the result.
 Support for both top-down development and more
traditional bottom-top development.
 Easier refactoring and code modification.
