SEMINAR ON DYNAMIC LANGUAGES : It is a class of programming languages, which have characteristics of high-level, dynamically typed, open source. These languages ​​are indicated in the past by some as "scripting languages", and others are "general-purpose programming languages." None of the moniker accurately reflect the real strengths of these languages. We suggest that the term "dynamic language" as a term that evokes both the compact strengths of technical language and social force in their communities, participants and users.
This paper will argue that a lot of pressure on software systems such as the thrust of the standards conform to open systems and competitive advantages granted to the measurement systems, combined with a passage from the CPU systems linked network systems, Dynamic languages ​​have prompted a critical role again. In addition to its traditional role of scripting tasks, these programming languages ​​have shown an unprecedented ability to build a diverse set of large software systems.
We believe that this change justifies the importance of replacing the term "scripting language" with the one that best describes the language, the nature and effect, and suggests the use of the phrase "dynamic language". The choice the word "dynamic" plus "scripting" is a pragmatic approach, the initial term has tended to minimize the wide range of usability of the language. The new term reflects the belief that the real world value of these languages ​​are derived most of their dynamics (technical and social) and their kindness.
Here, I present the essential features of dynamic languages, and the contrast with other language groups. Popular dynamic languages ​​are a brief survey, followed by an analysis of emergent properties in the current technical, social, economic and legal. We suggest software environments where most appropriate and least.
