I have this GorillaScript code to flatten arrays:
Array::compact := #
for filter value in this
value and (typeof value.isempty != 'function' or not value.isempty()) and (typeof value != 'object' or Object.keys(value).length != 0)
GorillaScript is kinda dead. Could someone translate this into LiveScript for me please? I'm quite new to LiveScript.
A literal translation would look something like this.
Array.prototype.compact = ->
[v for v in @ when v and (typeof v.isempty isnt \function or not v.isempty!) and (typeof v isnt \object or Object.keys value .length > 0)]
A more idiomatic example might be:
is-empty = ->
| not it => false
| typeof it.isempty isnt \function or not it.isempty! => true
| typeof it isnt \object or not Object.keys it .length > 0 => true
| otherwise => it
Array.prototype.compact = -> [x for x in @ when not is-empty x]
Watch out, as this was done off the top of my head any my LiveScript's a bit rusty, but the general ideas here are ok.
