[英]TypeError: (fn) is not iterable when just executing a function
So I have a very simple code:所以我有一个非常简单的代码:
// doesn't matter, just be sure that we have an array
const tasks = Array.isArray(result) ? [...result] : [result];
// works
for (let i = 0; i < tasks.length; i++) {
this.executeNativeCommand(tasks[i].command, ...tasks[i].args);
}
// TypeError: this.executeNativeCommand is not iterable (cannot read property Symbol(Symbol.iterator))
tasks.forEach(task => {
this.executeNativeCommand(task.command, ...task.args);
});
Also tried this['executeNativeCommand']
— it worked.还尝试this['executeNativeCommand']
- 它有效。 What sort of magic is it?这是什么魔法?
The message is wrong and confusing, it should be tasks[i].args is not iterable
/ task.args is not iterable
.消息错误且令人困惑,应该是tasks[i].args is not iterable
/ task.args is not iterable
。
You probably ran into this V8 bug .您可能遇到了这个 V8 错误。
It was fixed three months ago (February 2020), but it seems it hasn't landed in stable node.js or Chrome yet.它是在三个月前(2020 年 2 月) 修复的,但它似乎还没有登陆稳定的 node.js 或 Chrome。
