1.直接比较字符串大小

<script type="text/javascript">
            const _shouldUpdate = (oldVersion, newVersion) => {
                // 补全代码
                return newVersion>oldVersion
            }
        </script>

2.利用split切割成数组再比较

<script type="text/javascript">
            const _shouldUpdate = (oldVersion, newVersion) => {
                // 补全代码
                return newVersion.split('.')>oldVersion.split('.')
            }
        </script>

3.切割为数组再拼接成字符串比较

<script type="text/javascript">
  const _shouldUpdate = (oldVersion, newVersion) => {
                // 补全代码
                return newVersion.split('.').join('')>oldVersion.split('.').join()
            }
</script>
