Ionic 4 app not working in android Lollipop

Question

I created an Ionic 4 android app which is working fine in Android 8. But when I test it in Android 5 (As an app and in the browser both), getting the below error.

Uncaught SyntaxError: Use of const in strict mode.       vendor.js:71605

Enabled polyfill.ts, but that didn't help.

How can I get rid of this?

There is a bug with Ionic 4. https://github.com/ionic-team/ionic/issues/15438 Not sure why people are down voting. — Santosh Hegde, Sep 06 '18 at 06:41

You might want to compile to ES2015.

Try adding this:

tsconfig.json
{
  "compilerOptions": {
    "module": "es2015",
    "target": "es2015"
  }
}

Uncaught SyntaxError: Unexpected reserved word vendor.js:140 Uncaught SyntaxError: Use of const in strict mode. main.js:104 2 errors are there now! – Santosh Hegde Sep 02 '18 at 08:06
Did you try this and build the app again? – SiddAjmera Sep 02 '18 at 08:19

if you use require declaration change it to import

import {foo} from 'bar'; Is equivalent to: var foo = require('bar').foo;
