The basic building block of the Abstract Syntax Tree (AST). In general a
Node represents non-terminals in the language grammar; however, some terminals are kept in the tree such as identifiers and literals.
Two key things make up an AST node's documentation. The node's
SyntaxKind which identifies its type within the AST, and its
interface, the API the node provides when instantiated into the AST.
Here are a few key
interface Node members:
TextRangemembers that identify the node's
endin the source file.
parent?: Nodethe parent of the node in the AST.
There are other additional members for
Node flags and modifiers etc. that you can lookup by searching
interface Node in the source code but the ones we mentioned are vital for node traversal.
SourceFile is a top-level AST node that is contained in the
