选项​

🌐 Options

importPolyfill​

boolean，默认值为 false。

默认情况下，这个插件只会转化提案语法，使用 Record 和 Tuple 全局变量：

🌐 By default this plugin only transforms the proposal syntax, using the Record and Tuple globals:

JavaScript
let a = #[1, 2, 3];

// ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇

let a = Tuple(1, 2, 3);

你要么需要加载一个 polyfill，要么可以传递 "importPolyfill": true 选项将导入注入到 @bloomberg/record-tuple-polyfill，由提案作者维护：

🌐 You either need to load a polyfill, or you can pass the "importPolyfill": true option to inject imports to @bloomberg/record-tuple-polyfill, maintained by the proposal authors:

babel.config.json
{
  "plugins": [
    [
      "@babel/plugin-proposal-record-and-tuple",
      {
        "importPolyfill": true
      }
    ]
  ]
}
JavaScript
let a = #[1, 2, 3];

// ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇

import { Tuple as _Tuple } from "@bloomberg/record-tuple-polyfill";

let a = _Tuple(1, 2, 3);

别忘了在你的依赖里加上 @bloomberg/record-tuple-polyfill！

🌐 Don't forget to add @bloomberg/record-tuple-polyfill to your dependencies!

polyfillModuleName​

string，默认值为 "@bloomberg/record-tuple-polyfill"。

如果你想给不同于 @bloomberg/record-tuple-polyfill 的 polyfill 注入 imports，你可以使用这个选项来指定它的名字。

🌐 If you wish to inject imports to a polyfill different from @bloomberg/record-tuple-polyfill, you can use this option to specify its name.
