JavaScript 使用正则表达式在长字符串中查找单词 "19XX"或 "18XX"

Question

我试图通过字符串来查找 19XX 或 18XX 格式的日期，其中 XX 可以是任何整数。这是基本设置:

var myLongString = "The Cold War (Russian: Холо́дная война́, Kholodnaya voĭna) was the continuing state from roughly 1946 to 1991 of political conflict...";

function getDates(myLongString) {
    //use regular expressions to create a list of words in the "19XX" or "18XX" format
    //and then return that list

}

感谢您的帮助。
