钉钉手机端chrome69版本的不支持??和?.语法

选择的前端框架，放到钉钉手机端浏览器报错，大概率是浏览器不支持??和?.
听说babel可以把编译代码成兼容格式，小菜不知道怎么用，求指导
我已经尝试了如下操作，还是不行：
package.json

babel.config.json


{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "browsers": ["> 0.25%", "not dead"]

}

然后

babel确实可以，packagezhong1uzhihon,仅仅在vs上单点调试过，没有运行环境看不到具体结果:

这篇博客: JS拓展：Babel(解决低版本浏览器对es语法的兼容)中的 在package.json文件的脚本中配置转义命令 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
1. 创建项目目录babelTtest
2. 在根目录下创建一个package.json文件，可以手动填写，也可以通过命令cnpm init --yes自动生成（也可以不显式的创建，执行下面命令后会自动的创建package.Json文件）
```
cnpm init --yes
```
1. 在当前目录执行x下列命令，以便于安装babel-cli命令行工具（此为开发依赖）
```
cnpm install babel-cli babel-preset-env --save-dev 
```
1. 创建 .babelrc 文件，如下
```
{
 "presets": ["env"]
}
```
1. 在你的 package.json 中添加一个 “scripts” 属性并将 babel 命令放在它的 build 属性中，如下（src等目录名根据你自己实际情况写）：
```
 "scripts": {
     "build": "babel src -d lib"
   },
```
1. 运行以下命令，开始转译
```
npm run build
```

引用chatGPT作答，是的，babel 可以将新版的 JavaScript 代码转换成较老版本的兼容代码，以适配不同的浏览器。下面是如何使用 babel 的简单指南：

1.安装 babel

npm install --save-dev @babel/core @babel/cli @babel/preset-env

2.在项目根目录下创建 .babelrc 文件，指定转换规则

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "chrome": "58",
          "ie": "11"
        }
      }
    ]
  ]
}

以上例子中，我们指定将 JavaScript 转换为支持 Chrome 58 和 IE 11 以上浏览器版本的代码。

3.修改 package.json，为 scripts 添加转换脚本

{
  "scripts": {
    "build": "babel src -d dist"
  }
}

以上脚本将会将 src 目录下的 JavaScript 代码转换后输出到 dist 目录下。

执行 npm run build 即可开始转换代码。

另外，您也可以使用 babel-loader 和 webpack 配合，将 babel 作为 webpack 的一个 loader，从而在打包时自动进行代码转换。
