What Go Programming Language does and does not have
Go has the benefit of hindsight, and basics are well done: it has a garbage collection, a package system, first class functions, lexical scope, a system call interface and immutable strings in which text are generally encoded in UTF-8. But it has comparatively few features and is unlikely to add more. For instance, it has no implicit numeric conversions, no constructors or destructors, no operator overloading, no default parameter values, no inheritance, no generics, no exceptions, no macros, no function annotations and no thread-local storage.
Before you read: This above passage is from the book “The Go Programming Language” by Alan A. A. Donovan and Brian W. Kernighan. page xiv . The points mentioned below are a brief and somewhat incomplete explanation of terms used in programming language design. I have tried to explain all the concepts from the angle of Go programming. All the points mentioned below are not mine, they are taken from the passage. I am in no way advocating for Go or any other language.
We will now try to understand each term in brief. As a beginner in core programming, having knowledge of these terms are important. The meaning of all these concepts apply in every programming language. These terms can help you distinguish various languages on a fundamental level.
