类名称：VariableDeclaration

VariableDeclaration介绍

[英]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 truefrom its #isStatement() method.
[中]一个或多个var、const或let声明的列表。节点类型为Token#VAR、Token#CONST或Token#LET。
如果节点用于var或const，则节点位置是var或const关键字的开头。对于let声明，节点位置与第一个VariableInitializer子节点一致。
语句上下文中的独立变量声明从其#isStatement（）方法返回True。
