In my Coffeescript code, I am successfully using array destructuring like this:
[first, second, third] = [1, 2, 3]
console.log "First:" + first, "Second:" + second, "Third:" + third
However, I now have a need to ignore an element in the array. I want to do something similar to this:
[, second, third] = [1, 2, 3]
console.log "Second:" + second, "Third:" + third
This kind of operation can be easily achieved in EcmaScript 6, but how can I accomplish it in Coffeescript?
After experimenting, I discovered a neat trick for achieving this! By utilizing the expansion operator, it's possible to easily extract specific elements from an array:
[..., middle, end] = [5, 6, 7]
console.log "Middle:" + middle, "End:" + end
