示例1: __rebuildAsAssignment

# 或者: from jasy.js.parse.Node.Node import replace [as 别名]

"""Rebuilds the items of a var statement into a assignment list and moves declarations to the given var statement"""
assignment = Node(node.tokenizer, "semicolon")

for child in list(node):

# Cleanup initializer and move to assignment
if hasattr(child, "initializer"):

# It is OK to be second because of assignments are not allowed at
# all in for-in loops and so the first if basically does nothing
# for these kind of statements.
