SyntaxError in Chrome/39.0.0.0

[chenyulun]

Stencil version:

 @stencil/core@1.17.3<version>

I'm submitting a:

[x] bug report [ ] feature request [ ] support request => Please do not submit support requests here, use one of these channels: https://stencil-worldwide.herokuapp.com/ or https://forum.ionicframework.com/

Current behavior:

SyntaxError: in strict mode code, functions may be declared only at top level or immediately within another function

Expected behavior:

Old browsers should be able to load the polyfills.

Steps to reproduce:

Open a simple page using on Chrome/39.0.0.0 "Mozilla/5.0 (Linux; Android 5.1.1; vivo X7 Build/LMY47V) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/39.0.0.0 Mobile Safari/537.36 MyAppHybrid/3.4.0 (MYAPPNAME 4.39.0) UnionPay/1.0 MYAPPNAME deviceId/AUUID_d0d6a8dc52d4247cc815328f5d72cca9b7abb81e deviceType/1 device-dpr/3.0 device-dr/640.0*360.0 networkState/WIFI" The stenciljs generated file won't be loaded and no custom element is defined in the page.

Related code:

// insert any relevant code here

'use strict';
(function () {
  var currentScript = document.currentScript;

  // Safari 10 support type="module" but still download and executes the nomodule script
  if (!currentScript || !currentScript.hasAttribute('nomodule') || !('onbeforeload' in currentScript)) {

If I comment out the if statement, it works fine

I now have slotChildNodesFix:false in my configuration, I think this fix should determine whether the browser has native methods to determine whether or not it is fixed

chrome39 and chrome89 canary can cache childNodes using variables. The cache variables will change synchronously when the element changes

Hey there! 👋

I'm sorry it took someone this long to get to this ticket. The Stencil team is currently only supporting Stencil 2.0+. As of Stencil 2.0, Chrome 39 is not supported. . I'm going to close this ticket, and apologize again for how long it went unacknowledged.
