我看到您添加了一个 polyfill 来解决问题，但您的问题的答案是 NetSuite/SuiteScript 使用 ECMAScript 5.1；它的引擎是 Java Rhino(不确定是哪个版本).

I see you added a polyfill to solve the problem, but the answer to your question is that NetSuite/SuiteScript uses ECMAScript 5.1; its engine is Java Rhino (unsure which version).

find 是在 ES6 中加入的，而 reduce 是在 ES5.1 中加入的，所以 SuiteScript 不支持 find 而支持 减少代码>.

find was added in ES6, while reduce was added in ES5.1, so SuiteScript does not support find while it does support reduce.
