			<ul>
			<li>Probably the main use of NumberByName is to determine if a given name is present in an object. Since the [[Item (Json property)\|Item property]] will return a null if either the requested name is not present in the object or if the value associated with that name is null, NumberByName is one way to distinguish those cases.</li>
			</ul>
	==Examples==		==Examples==
			The following example populates an object with some values and then retrieves the values for names "Ostrich" and "Diplodocus". As you can see, the values are identical. However, the NumberByName method values for "Ostrich" and "Diplodocus" reveal the one is in the object but set to null while the other is simply not in the object.
			<p class="code">b

			%json is object json

			%json = object
			%json("Tiger") = "Asia"
			%json("Lion") = "Africa"
			%json("Diplodocus") = null
			%json("Elk") = array("North America", "Asia")
			%json("Kangaroo") = "Australia"

			printText {~=%json("Ostrich")}
			printText {~=%json("Diplodocus")}
			printText {~=%json:numberByName("Ostrich")}
			printText {~=%json:numberByName("Diplodocus")}

			end
			</p>
			This prints:
			<p class="code">%json("Ostrich")=null
			%json("Diplodocus")=null
			%json:numberByName("Ostrich")=0
