Similar to type, this method returns a symbol that you can use for splitting on the type of the node without having to do a long === chain. Note that like type, it will still be slower than using == for a single class, but should be faster in a case statement or an array comparison.
def self.type: () -> Symbol
def initialize: (parent: Node?, child: Node, delimiter_loc: Location, location: Location) -> void
def accept: (visitor: Visitor) -> void
def child_nodes: () -> Array[nil | Node]
def delimiter: () -> String
Sometimes you want to check an instance of a node against a list of classes to see what kind of behavior to perform. Usually this is done by calling ‘[cls1, cls2].include?(node.class)` or putting the node into a case statement and doing `case node; when cls1; when cls2; end`. Both of these approaches are relatively slow because of the constant lookups, method calls, and/or array allocations.
Instead, you can call type, which will return to you a symbol that you can use for comparison. This is faster than the other approaches because it uses a single integer comparison, but also because if you’re on CRuby you can take advantage of the fact that case statements with all symbol keys will use a jump table.

def self.type: () -> Symbol
Returns the list of parts for the full name of this constant path. For example: [:Foo, :Bar]
Returns the full name of this constant path. For example: “Foo::Bar”
