Promise.finally is undefined

[luhc228]

When I set the "useBuiltIns": "entry", the Promise.prototype.finally is undefined. When I set the "useBuiltIns": "usage"，I can use the promise.prototype.finally.

how to solve this problem.

When you use "useBuiltIns": "entry", you should import required modules by yourself, for example, use import 'core-js/stable', and preset-env will optimize it.

The order may not be right now. The Promise.finally is before the Promise, which will be overrided.

In this case, it's a Babel issue, you could report it here https://github.com/babel/babel-polyfills/
