# Zero Values

Variables declared without an explicit initial value are given their zero value.
The zero value is:

0 for numeric types,
false for the boolean type, and
"" (the empty string) for strings.
nil for slice

s := "" 
s := make([]string, 3) //[   ]
var s string 
var s = "" 
var s string = ""
