Course Introduction:Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel computing model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages that adopt similar models include Occam and Limbo. Go also has the characteristics of this model, such as channel transmission. Compared with C++, Go does not include functions such as enumeration, exception handling, inheritance, generics, assertions, virtual functions, etc., but it adds features such as slice type, concurrency, pipelines, garbage collection functions, interfaces, etc. level support. Unlike Java, Go natively provides associative arrays (also called hashes or dictionaries), just like string types.
