Video Description

Build foundation for your applications with the basic understanding of Go

About This Video

  • Discover a number of solutions and approaches to develop modern back-end applications

  • Put to use the best practices to combine the solutions for sophisticated parallel tools

  • This video is based on Go version 1.6 and above

    • In Detail

    Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library.

    This course takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers.

    The course covers basic type and error handling. It explores applications that interact with users, such as command-line tools or via the file system.
