现在我们可以使用Intl了。Collator API现在创建数值比较器。浏览器支持是相当不错的，但在撰写本文时，Node.js还不支持。

const semverCompare = new Intl。Collator("en"， {numeric: true}).compare; const版本=[1.0.1,“1.10.2”,“1.1.1”,‘1.10.1’,‘1.5.10’,‘2.10.0’,‘2.0.1’); console.log (versions.sort (semverCompare)) const example2 =(“1.0”,“1.0.1”,“2.0”,“2.0.0.1”,“2.0.1”); console.log (example2.sort (semverCompare))

你可以遍历每个以句点分隔的字符并将其转换为int类型:

var parts = versionString.split('.');

for (var i = 0; i < parts.length; i++) {
  var value = parseInt(parts[i]);
  // do stuffs here.. perhaps build a numeric version variable?
}

这个非常小，但非常快的比较函数接受每个段的任何长度和任何数字大小的版本号。

返回值: -如果a < b，则数字< 0 -如果是> b，则为> 0 如果a = b - 0

所以你可以使用它作为array。sort()的比较函数;

编辑:修正了版本剥离尾随零识别“1”和“1.0.0”相等的错误
