Initializing variables in Go
Normal initialization
var myStr string = "mystring"
var myInt int = 10
If you don't explicitly initialize a variable with a value, it will get the zero value for it's type.
var myStr string // myvar == ""
var myInt string // myvar == 0
Short initialization
Short initialization is performed using the := operator. It can only be done within a function, and the type of the variable is inferred from the value assigned to it.
myStr := "mystring"
myInt := 10
