Value assignment

var s1 string         // a new string identifer with its zero value ("")
var s2 string = "foo" // an identifer with a non-zero value
var i1 int            // an int identifer with its zero value (0)
var i2 int = 42       // an int identifer with a non-zero value

2015-08-20: Go Workshop Notes

• Workshop run by Bill Kennedy
• Course materials available at https://github.com/ardanstudios/gotraining
• This was a one-day distillation of the full 3-day course

Variables and Types

• Type gives the compiler two things: size + representation. The compiler guarantees these types
