le( )

Refines a query to match items whose specified property value is less than or equal to the specified value.

The le() function refines a ContactsQueryBuilder to only match items where the value of the specified property is less than or equal to the specified value.

It only matches values of the same type. For example, a number value stored as a String type does not match the same number stored as a Number type.

If a property contains a number as a String, that value will be compared alphabetically and not numerically. Items that do not have a value for the specified property are ranked lowest.

The following types of properties can be compared:

• Number: Compares numerically.
• Date: Compares JavaScript Date objects.
• String: Compares lexicographically, so "ABC" is less than or equal to "abc" (because of the less than), but "abc" is not less than or equal to "ABC".
