[Android] Running the for statement in the JavaScriptcore takes a lot of time

[st-dc]

JS sample code： var start = new Date().valueOf() var arr = [] for (var i = 0; i < 100000; i++) { var arrIn = [] for (var j = 0; j < 1000; j++) { arrIn.push(j) } arr.push(arr) } var end = new Date().valueOf() console.log("time：" + (end - start) + "ms") JavaScriptCore takes 19000ms to complete. The system WebView runs JS sample code, which only needs 3000ms to complete。 Please change JSC to V8!!!!!

From Weex 0.28, you can choose whaterver JS interpertator you want as long as you implement a group of interface.

You could:

• Use release version of your app instead of debug version. Debugbable Apps usually have performance punishment.
• Upgrade JSC version as you wish.
• Implement the interface with V8 and give us a Pull request.

既然都知道有性能问题，官方为何还不更新优化？ 这样才会更多人使用，吸引更多人贡献代码呀 @YorkShen

“我不是v8或jsc的员工”？这个说法，好不专业啊。 这就是淘宝的工程师吗？ 淘宝有没有领导在关注这个事情？ 如此慢的js引擎，你们内部使用时怎么过的性能测试？ 你提供了项目只有jscore，你倒是再提供一个v8的样例啊！！！

1. Apache Weex 现在和淘宝无关(尽管源自淘宝)
2. 我不是淘宝的员工，现在没有任何人付钱(包括你在内)给我做 Apache Weex。
3. Talk is cheap, show your code.
