请问为何babel转换await async后，代码内有Promise？

asked Jan 27, 2021 in Technique[技术] by 深蓝 (71.8m points)

Promise不是ES6的内容吗？
babel不应该转换成ES5吗？

babel的配置

presets: ['@babel/preset-env', '@babel/preset-react'],
plugins: ['@babel/plugin-syntax-dynamic-import'],

@babel/preset-env 默认只转ES语法，Promise是新的api，需要引入@babel/polyfill方案去解决
