Visão Geral

Curso Go Programming A linguagem de programação Go (também conhecida como Golang) é amplamente usada no Google (que convidou a linguagem) e está crescendo em popularidade para o desenvolvimento do lado do servidor (incluindo microsserviços).

Nosso Curso Go Programming, lhe dará uma introdução a esta popular linguagem de programação e mostrará como aplicar programação funcional baseada em objetos e técnicas de simultaneidade.

Este curso também serve como uma base sólida para avançar para o desenvolvimento de servidores da web baseados em Go, serviços Go, microsserviços Go etc.
