"less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order.

+			<return type="String" />
+			<param index="0" name="values" type="Variant" />
+			<param index="1" name="placeholder" type="String" default="&quot;{_}&quot;" />
+			<description>
+				Formats the string by replacing all occurrences of [param placeholder] with the elements of [param values].
+				[param values] can be a [Dictionary] or an [Array]. Any underscores in [param placeholder] will be replaced with the corresponding keys in advance. Array elements use their index as keys.
+				[codeblock]
+				# Prints: Waiting for Godot is a play by Samuel Beckett, and Godot Engine is named after it.

+
+				# Prints: User 42 is Godot.
+				print("User {id} is {name}.".format({"id": 42, "name": "Godot"}))
+				[/codeblock]
+				Some additional handling is performed when [param values] is an array. If [param placeholder] does not contain an underscore, the elements of the array will be used to replace one occurrence of the placeholder in turn; If an array element is another 2-element array, it'll be interpreted as a key-value pair.
+				[codeblock]
+				# Prints: User 42 is Godot.
+				print("User {} is {}.".format([42, "Godot"], "{}"))
+				print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))

+			</description>
+		</method>
+		<method name="get_extension" qualifiers="const">
+			<return type="String" />
+			<description>
+				Returns the extension without the leading period character ([code].[/code]) if the string is a valid file name or path. If the string does not contain an extension, returns an empty string instead.
+				[codeblock]
+				print("/path/to/file.txt".get_extension())  # "txt"
+				print("file.txt".get_extension())  # "txt"
+				print("file.sample.txt".get_extension())  # "txt"

+			<description>
+				Splits a string using a [param delimiter] and returns a substring at index [param slice]. Returns an empty string if the index doesn't exist.
+				This is a more performant alternative to [method split] for cases when you need only one element from the array at a fixed index.
+				[b]Example:[/b]
+				[codeblock]
+				print("i/am/example/string".get_slice("/", 2)) # Prints 'example'.

+				Splits the string by a [param delimiter] string and returns an array of the substrings, starting from right. If [param delimiter] is an empty string, each substring will be a single character.
