coffeescript如何在python中像"元组"一样解压缩

Question

我是coffeescript的新手.有没有办法让这三行设置旋转并完成相同的事情,就像你在python中通过解压缩元组一样？

@cosines = [0,1,0]
@branch.rotation.x = Math.asin(@cosines.x)
@branch.rotation.y = Math.asin(@cosines.y)
@branch.rotation.z = Math.asin(@cosines.z)

Answer 1

这是我能想到的最好的代码.

@cosines = [0,1,0]
rot = @branch.rotation
[rot.x, rot.y, rot.z] = [Math.asin(c) for c in @cosines]

该拆包 解构是一样的Python,但用方括号.
