Empty string: Difference between revisions

=={{header|Fantom}}==

Fantom uses "" to represent an empty string, and provides the isEmpty method to check if a string is empty.

<lang fantom>

a := "" // assign an empty string to 'a'

a.isEmpty // method on sys::Str to check if string is empty

a.size == 0 // what isEmpty actually checks

a == "" // alternate check for an empty string

!a.isEmpty // check that a string is not empty

</lang>
