Say I have an array of arrays, and I want to return the first element of each array within the array:
array = [[[028A,028B,028C,028D,028E],
[028F,0290,0291,0292,0293],
[0294,0295,0296,0297,0298],
[0299,029A,029B,029C,029D],
[029E,029F,02A0,02A1,02A2]],
[[02A3,02A4],
[02A5, 02A6]];
I know I can do something like this:
var firsts = [];
_.each(array, function(item){
_.each(item, function(thisitem){
firsts.push(_.first(thisitem));
});
});
but what if I want to do it with underscore's _.chain()
method? Just learning underscore, and so far seems very useful.
