if (process.env.NODE_ENV === "production") {
  plugins.push("transform-remove-console");
}
module.exports = {
  plugins: [
    ...plugins,
    // es2020 ?.
    "@babel/plugin-proposal-optional-chaining",
    // es2020 ??
    "@babel/plugin-proposal-nullish-coalescing-operator"
    /*[
      "component",
      {
        libraryName: "element-ui",
        style: false
      }
    ]*/
