Tag: JavaScript object class

An object type is a user-defined composite datatype that encapsulates a data structure along with the functions and procedures needed to manipulate the data . The variables that form the data structure are called attributes.

You can check the type of a variable by using the gettype() function . Just pass in the variable whose type you want to test and get the variable’s type as a string. The $var variable initially has a type of null , because it has been created but not initialized by assigning a value.
