Type detection is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
This draft task needs a purpose, a description and some way to tell whether examples satisfy or do not satisfy it.
JavaScript
console.log(typeof('foo')); // Returns string
console.log(typeof(12345)); // Returns number
OASYS Assembler
<lang oasys_oaa>
- The following method checks if a global variable or property is an
- object type. Does not work with locals and arguments.
[&OBJ#,^]
,^<,^<< ; Remember old value ,^<*> ; Create new object ,^<<DES ; Destroy the object ,^<<EX ; Check if variable has been cleared />1RF ; It is clear :>0RF ; It is not clear
</lang>
PHP
echo gettype('foo'); // Returns string
echo gettype(12345); // Returns integer
