思路

以符号 . 分割字符串,再join('')拼接,转成数字比较大小

const _shouldUpdate = (oldVersion, newVersion) => {
                // 补全代码
                const oldNumber = Number(oldVersion.split('.').join(''))
                const newNumber =Number(newVersion.split('.').join(''))
                // console.log(oldNumber, newNumber)
                if (newNumber > oldNumber) {
                  return true
                }
                return false
            }
