Go has no special syntax for empty strings.
In Go variables are always initialized to a provided value or to the "zero value" of the type.
<lang go>// assign empty string to a variable▼
The zero value of a string is the empty string.
<lang go>// define and initialize an empty string
var s string
s2 := ""
s = ""
// check that a string is empty, any of:
s == ""
len(s) == 0
// check that a string is not empty, any of:
s
len(s) != 0 // or > 0</lang>
