你好来自 ecmascript specifications
UnicodeIDStart::
any Unicode code point with the Unicode property "ID_Start"
UnicodeIDContinue::
any Unicode code point with the Unicode property "ID_Continue"
什么是 Unicode 属性“ID_Start”和“ID_Continue”？
最佳答案
指的是Unicode character properties .作为the ES spec说
IdentifierName and ReservedWord are tokens that are interpreted according to the Default Identifier Syntax given in Unicode Standard Annex #31, Identifier and Pattern Syntax […]. The Unicode identifier grammar is based on character properties specified by the Unicode Standard.
That standard在 bibliography 中也被引用规范。
