Coffeescript数组销毁会忽略某些值

Question

I'm using array destructing in coffeescript and it working properly: 我在coffeescript中使用数组销毁，它可以正常工作：

[first, second, third] = [1, 2, 3]
console.log "First:" + first, "Second:" + second, "Third:" + third

but I want to be able to ignore array element. 但我希望能够忽略数组元素。 I want to do something like this: 我想做这样的事情：

[, second, third] = [1, 2, 3]
console.log "Second:" + second, "Third:" + third

This is possible in EcmaScript 6 but how to achieve this under Coffescript? 这在EcmaScript 6中是可能的，但是如何在Coffescript下实现呢？

Answer 1

I just find how to do this. 我只是找到如何做到这一点。 This can be done with expansion operator: 这可以通过扩展运算符完成：

[..., second, third] = [1, 2, 3]
console.log "Second:" + second, "Third:" + third
