The Wolfram Language supports immediate access to REPLs for external languages such as Python, JavaScript (Node.js), etc., as well as variants in which particular packages are preloaded. Once an external system is discovered or registered, ExternalEvaluate immediately calls the system, either in a one-shot mode or through a persistent session.

ExternalEvaluate — one-shot evaluation of external code

ExternalFunction — call a function in an external language, and return the result

ExternalOperation — represents an external operation

ExternalObject — represents an external object bound to an external session

External Sessions

StartExternalSession — start a persistent session of the external system

ExternalSessionObject — symbolic representation of an active external session

ExternalSessions — give a list of active external sessions
