Use of semicolons in ES6
提问by seven11
I was under the impression semicolons became obsolete with ES6. However, I came across this today:
我的印象是分号在 ES6 中已经过时了。然而，我今天遇到了这个：
Doesn't work:
不起作用：
let i = 0
[0, 1, 2, 3, 4, 5, 6].forEach(item => console.log(item))
Works:
作品：
let i = 0;
[0, 1, 2, 3, 4, 5, 6].forEach(item => console.log(item))
Why is the semicolon necessary here, and when should I use them?
为什么这里需要分号，我应该什么时候使用它们？

Without the semicolon [1,2,3,4,5,6] will be evaluated as property access. Which is perfectly fine JS, I personally don't think that adding semicolons is such a big deal so I keep using them.
没有分号 [1,2,3,4,5,6] 将被评估为属性访问。这是非常好的 JS，我个人认为添加分号不是什么大问题，所以我继续使用它们。
