.hastype

localDataStorage.hastype( dataType )

This checks the store for the existence of dataType and returns true or false (query by type).

EXAMPLE:

● localData.hastype( 'float' )   -->   true

Any of the following options can be used to query the store by type: array, bigInt, boolean, date, float, integer, null, number, object or string.

To determine if a certain value exists in the store, use hasval, and to see whether a key exists, use haskey.
