Empty string: Difference between revisions

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.

The zero value of a string is the empty string.

<lang go>// define and initialize an empty string

var s string

s2 := ""

// assign an empty string to a variable

// check that a string is empty, any of:

len(s) == 0

// check that a string is not empty, any of:

s != ""

len(s) != 0 // or > 0</lang>
