sourceTextModule.hasAsyncGraph()
遍历依赖图,如果依赖中的任何模块或本模块本身包含顶层 await
表达式,则返回 true
,否则返回 false
。
¥Iterates over the dependency graph and returns true
if any module in its
dependencies or this module itself contains top-level await
expressions,
otherwise returns false

如果图足够大,搜索速度可能会很慢。
¥The search may be slow if the graph is big enough.
这需要先实例化模块。如果模块尚未实例化,则会抛出错误。
¥This requires the module to be instantiated first. If the module is not instantiated yet, an error will be thrown.
