Go Cheatsheet

Apa itu GO?

APakah ini bagian dari Gojek? Oh ternyata bukan lol… Go adalah bahasa pemrograman yang dibuat oleh Google pada tahun 2007. Sejak saat itulah mereka memutuskan untuk mengimplementasikan Go untuk membuat produk dan servis dalam skala besar.

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It’s a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

• Go is an open source programming language supported by Google
• Easy to learn and get started with
• Built-in concurrency and a robust standard library
• Growing ecosystem of partners, communities, and tools
