Summary

• Statically compiled typed language.
• Outputs binary executables.
• Created in 2007 at Google by authors such as Ken Thompson who made C.
• Go has been described as C for the 21st century.
• It had speed as a compiled language, like C or Rust.
• It also improves on older languages with faster compile times.

Types

It is efficient in running and also the code - types can often be inferred so your code isn’t verbose.

Both are valid in Go:

var string foo = "abc"

foo := "abc"
