Observaçõs iniciais

Além de aprender a programar com a linguagem desejada/plataforma desjeada, é fortemente recomendado se qualifique no idioma inglês. Em termos de oportunidade de trabalho, ter uma boa comunicação no inglês é tão importante quanto saber programar bem. Além disso, a maior parte do conteúdo de boa qualidade é escrita neste idioma.

Para acelerar seu aprendizado, não estude apenas, estude e tente praticar o máximo fazendo exercícios e projetos.
