// Add 'use strict' to the bundle, https://github.com/angular/angular/pull/40456
|
|
// When rollup build esm bundle of zone.js, there will be no 'use strict'
|
|
// since all esm bundles are `strict`, but when webpack load the esm bundle,
|
|
// because zone.js is a module without export and import, webpack is unable
|
|
// to determine the bundle is `esm` module or not, so it doesn't add the 'use strict'
|
|
// which webpack does to all other `esm` modules which has export or import.
|
|
// And it causes issues such as https://github.com/angular/angular/issues/40215
|
|
// `this` should be `undefined` but is assigned with `Window` instead.
