Go or you say Golang is a procedural and statically typed programming language having the syntax similar to C programming language. It was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson at Google but launched in 2009 as an open-source programming language and mainly used in Google’s production systems. Golang is one of the most trending programming languages among developers. It provides a rich standard library, garbage collection, and dynamic-typing capability.

    • Identifiers in Go Language
      In programming languages, identifiers are used for identification purposes. In other words, identifiers are the user-defined names of the program components. In the Go language, an identifier can be a variable name, function name, constant, statement label, package name, or type. Example: package ma

    • Go Keywords
      Keywords or Reserved words are the words in a language that are used for some internal process or represent some predefined actions. These words are therefore not allowed to use as an identifier. Doing this will result in a compile-time error. Example: C // Go program to illustrate the // use of key
