whichType(value)

Determine the type of parameter(value)

Accepted parameter(value) type: Any
Type of value returned: Object
- typeof: Value is typeof value
- prototype: The last bit type with value Object.prototype.toString.call(value)

Example:

type.whichType('');

/* return
{
  typeof: "string",
  prototype: "String"
}
*/

type.whichType(Promise.resolve());

/* return
{
  typeof: "object",
  prototype: "Promise"
}
*/
