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

[1]

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

[2]

echo gettype('foo'); // Returns string
echo gettype(12345); // Returns integer
