Is this a regression?
Yes, the previous version in which this bug was not present was: ....build-optimizer: 0.800.1 works fine.
Description
A clear and concise description of the problem...It seems #14585 breaks below syntax
export default class Foo { .. }
after this change, it converts that code to
export default const Foo = { .. }
export default const is not valid syntax. ng build --prod failed with above code in parsing by acorn cause of that syntax.
🔬 Minimal Reproduction
execute ng build --prod with this project
https://github.com/kawamoto/ng-export-default-class
🔥 Exception or Error
ERROR in ./src/app/foo.js 1:15
Module parse failed: Unexpected token (1:15)
You may need an appropriate loader to handle this file type.
> export default const Foo = /*@__PURE__*/ (() => {
| class Foo {
| constructor() {
