GetTypeOf()
Posted: Fri Sep 11, 2015 5:12 pm
With JavaScript, the TypeOf() function returns the datatype of the data contained in parameter.
For example, if I debug typeof ("test") the result is a String.
View result http://jsfiddle.net/falsam/xg3acvqs/
With PureBasic, it is not possible. It must pass a parameter with a datatype.
This short code is a workaround.
