DYNAMIC LANGUAGE
[attachment=16191]

Introduction

is a term used broadly in computer science

execute at runtime

modifying the type system, all during program execution


Static vs. Dynamic Languages

Static Languages

Type safety

Compile-time checking

Runtime performance

Syntactic Sugar 

Dynamic Languages

Late bound

Loosely typed

Highly expressive


Features

High Level Features

Built in Data Types

The two universal data types are lists and strings

Most dynamically typed languages also provide support for dictionaries and

sets.


Hosting API


Script Runtime

Starting point for hosting

Represents global script state

Bound scopes

Constructed with Script Runtime Setup,

Script Engine

Represents a DLR language implementation

One engine, per-language, per-runtime which uses configuration settings


Advantages

Provide extensibility (the obvious answer)‏

Replace complicated XML configuration with meaningful code

Remove clutter from core application logic

Maintain transient logic outside of core application code

Disadvantages

Performance

Debugging

Code completion

Types as documents

Conclusion

Functional programming concepts are used.

The assertion that a language is dynamic is more an assertion about the ease of use of dynamic features than it is a clear statement of the capabilities of the language.
