 * This file is divided into 2 sections:

 *
 * The current setup is for so-called "evergreen" browsers; the last versions of browsers that

ng new myapp ng serve

Observed behavior

Give this error on IE10
SCRIPT1002: Syntax error

Desired behavior

Should work with IE10.

Mention any other details that might be useful (optional)

This application works well with Firefox, Chrome and IE11

When solving a compatibility problem in Safari, this issue seems to be fixed as well.

Solution comes from this stackoverflow post Default Angular-CLI Project Fails in Safari - culprit strict mode?

It seems an issue in webpack-dev-server (used under the hood by @angular/cli) which uses ES6 features and is not being transpiled. A temporary workaround is to use an older version for webpack-dev-server by installing it and copying it manually to the local @angular/cli directory:

yarn add webpack-dev-server@2.7.1 --dev
cp -R ./node_modules/webpack-dev-server ./node_modules/@angular/cli/node_modules/
ng serve

The error is due to the development server’s live reload client code (from webpack-dev-server) which requires basic ES2015 support. This will not affect builds (production or otherwise) of the application as the live reload code is not present. Live reload functionality can be disabled, if desired, via the --no-live-reload option. Due to a defect in safari 10, enabling source maps on ng serve (the default) results in a similar error. This does not affect Safari 11.
