Imagine I have a nested array structure.
var nested = [ [1], [2], [3] ];
Using underscore.js, how would I produce a flattened array?
In C# you would use Enumerable.SelectMany
like this:
var flattened = nested.SelectMany(item => item);
Note that the lambda in this case selects the nested item directly, but it could have been any arbitrary expression.
In jQuery, it's possible to just use:
var flattened = $.map(nested, function(item) { return item; });
However this approach doesn't work with underscore's map function.
So how would I get the flattened array [1, 2, 3]
using underscore.js?
var nested = [ [1], [2], [3] ];
var flattened = _.flatten(nested);
