I'm trying to covert javascript object to an array using Underscore, but I have some problems with understanding Underscore. I want to covert this:
{ key1: value1, key2: value2},{key1: value1, key2: value2}
Into this:
[value1, value2],[value1, value2]
You can use _.map and _.values like this
var data = [{ key1: 1, key2: 2 }, { key1: 3, key2: 4 }];
console.log(_.map(data, _.values));
# [ [ 1, 2 ], [ 3, 4 ] ]
If you fancy generic JavaScript version, you can do
console.log(data.map(function(currentObject) {
return Object.keys(currentObject).map(function(currentKey) {
return currentObject[currentKey];
})
}));
# [ [ 1, 2 ], [ 3, 4 ] ]
I suppose you're having input as Array of Objects and want the result in Array of Arrays, then you could just use native javascript to do it
var output = input.map(function(obj){ return [obj.key1, obj.key2] });
