Sintaksa e Go-s\u00eb \u00ebsht\u00eb e bazuar n\u00eb elemente t\u00eb njohura nga gjuha C me disa huazime nga gjuha Python.

Projekti zhvillohet fillimisht me fokus n\u00eb programimin me shum\u00eb procese dhe funksionimin efikas n\u00eb sisteme me shum\u00eb b\u00ebrthama, duke ofruar gjithashtu mjete t\u00eb implementuara n\u00eb nivelin e operator\u00ebve p\u00ebr organizimin e llogaritjeve paralel dhe nd\u00ebrveprimin nd\u00ebrmjet metodave q\u00eb ekzekutohen paralelisht.
