选项​

¥Options

boolean，默认为 false。

¥boolean, defaults to false.

默认情况下，此插件仅使用 Record 和 Tuple 全局变量转换提案语法：

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

// ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇

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

你需要加载一个 polyfill，或者你可以传递 "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);
