@babel/plugin-syntax-bigint

info

这个插件包含在 @babel/preset-env 中，在 ES2020 中

note

仅语法​

🌐 Syntax only

这个插件只启用对这个功能的解析。Babel 不支持转换 BigInt。一个建议是使用 JSBI 库，并最终运行 babel-plugin-transform-jsbi-to-bigint 将其在未来转换为 BigInt。

🌐 This plugin only enables parsing of this feature. Babel doesn't support transforming BigInts. One recommendation is to use the JSBI library and eventually run babel-plugin-transform-jsbi-to-bigint to codemod it to BigInt in the future.
