Notes on Golangbot Golang tutorial series.

The primary focus of Golang is to make the development of highly available and scalable web apps simple and easy.

• Concurrency
• Compiled
• Static linking
• Go Playground
• Linux based IDEs?
• Debuggers?
• Code analyzers?

Go does not allow automatic type promotion or conversion – “type conversion.”

bool (&&, ||)
string

int8  int16  int32  int64
int (32 or 64 depending)

uint8 uint16 uint32 uint64
uint (32 or 64 depending)

uintptr

float32 float64
complex64 complex128

byte // alias for uint8
rune // alias for int32

%T printf format specifier prints the type of something.

const i = 42

• Value assigned to const must be known at compile time; cannot require any function execution.
• Untyped constants have a default type associated with them and they supply it if and only if a line of code demands it. You can always created a typed constant if you want:

const typedhello string = "Hello World"

• return type follows parameter list
