移除vscode装饰器报错

使用vscode 创建一个 react+reducer项目时候，遇到以下警告

Experimental support for decorators is a feature that is subject to
change in a future release. Set the ‘experimentalDecorators’ option to
remove this warning.

解决办法：
在项目的根目录创建一个 tsconfig.json，配置如下：

{
    "compilerOptions": {
        "experimentalDecorators": true,
        "allowJs": true
    }
}

重新vscode即可
