java.lang.Object org.mozilla.javascript.Node org.mozilla.javascript.ast.AstNode org.mozilla.javascript.ast.VariableDeclaration
public class VariableDeclaration
A list of one or more var, const or let declarations.
Node type is Token.VAR
, Token.CONST
or
Token.LET
.
If the node is for var
or const
, the node position
is the beginning of the var
or const
keyword.
For let
declarations, the node position coincides with the
first VariableInitializer
child.
A standalone variable declaration in a statement context returns true
from its isStatement()
method.

AstNode
Note: if the parser was in error-recovery mode, some AST nodes may have
null
children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource
method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
