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

Question

我正在尝试通过字符串查找格式为19XX或18XX的日期，其中XX可以是任意整数。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。
