For example, given the following structure
pages = [
[
{ myvar: 1},
{ myvar: 2},
{ myvar: 3},
]
];
How can I express the folling (python-like) comprehension?
v.myvar for p in pages for v in p
AFAIK, you can not, see: https://github.com/jashkenas/coffee-script/issues/1191
A workaround in the meantime (until CoffeeScript gets improved):
pages = [
[
{ myvar: 1},
{ myvar: 2},
{ myvar: 3},
]
];
result = []
for row in pages
for map in row
result.push map.myvar
console.log result
which outputs:
[ 1, 2, 3 ]
