javascript - Coffeescript 数组解构忽略某些值

Question

我在 CoffeeScript 中使用数组解构并且它工​​作正常:

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

但我希望能够忽略数组元素。我想做这样的事情:

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

这在 EcmaScript 6 中是可能的，但如何在 Coffescript 下实现这一点？

Answer 1

我刚刚找到了如何做到这一点。这可以通过扩展运算符来完成:

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