javascript error differences on iphone 4 vs 6

[whimsica]

I had an array in javascript that was causing an error only on iphone 6 and 6 plus and not 4s or 5.
My webview javascripts wouldn't run but also gave no errors. window.onError did not catch anything.

The error was an extra comma in this statement
array=new Array("1","2",);

It took a long time to track down. Do you know why the errors would be different for different iphones? Is the webview different depending on the phone or version of ios?

Yes, if enableWKWebView is set true

unity-webview/sample/Assets/Scripts/SampleWebView.cs

Line 78 in 97293c8

enableWKWebView: true);

and the target iOS supports WKWebView, this plugin utilizes WKWebView. Otherwise it utilizes UIWebView. Perhaps your iPhone 4/5 have iOS 7.x or lower verions of iOS and UIWebView is utilized on them.
