What is The Difference Between BeanShell And ABCL, Programming Languages

BeanShell is a Scripting Language, while ABCL is a Concurrent Programming Language
What are Scripting Languages
Scripting languages are programming languages that control an application. Scripts can execute independent of any other application. They are mostly embedded in the application that they control and are used to automate frequently executed tasks like communicating with external programs.
What are Concurrent Programming Languages
Concurrent programming is a computer programming technique that provides for the execution of operations concurrently — either within a single computer, or across a number of systems. In the latter case, the term distributed computing is used. (Wikipedia)
While BeanShell is a Scripting Language, and ABCL is a Concurrent Programming Language
Let us now look at the difference between the two:
What is BeanShell Programming Language – A brief synopsis
It is a java scripting language that is syntactically similar to Java and runs on the Java Runtime Environment along with scripting commands and syntax.
What is ABCL Programming Language – A brief synopsis
It is actually a family of Actor-Based Concurrent Languages, which was developed in Japan during the 1980s and the 1990s. ABCL/1, ABCL/R, and ABCL/R2 are some members of the ABCL family.
