fromjs's Issues

bug: groupby changes type number to string without any reason

Hi,

I am using an array with numbers only.
When I group these numbers, the result function received it in a string.
It changes the type from number to string.

I created jsFiddle to show the problem

fromjs no "indexOf" function

var arr2 = [
{name: "a", color: "yellow"},
{name: "b", color: "red"},
{name: "c", color: "blue"},
{name: "c", color: "blue"}
];
var val2 = from(arr2).indexOf("$color==@","red");

//result:val2=1

Doesn't work properly in IE8

Set function context

A nice feature, though It might affect performance (minimal), would be the ability to set function execution context (this). In other words in ***Iterable.prototype.each functions using f.call(context,arg1,arg2,arg3,) instead of f(arg1,arg2,arg3) and similarly with non-eval'd proc lambdas. I can submit a pull request if this is something you might consider!

SelectMany+Concat Error

var petOwners = [
{ name: "ab", pets: [ "a", "b" ] },
{ name: "cd", pets: [ "c", "d" ] },
{ name: "ef", pets: [ "e", "f" ] }
];
from(petOwners).selectMany("$pets").concat(["x","y"]).toArray();

result:["a", "b", "c", "d", "e", "f"]
not ["a", "b", "c", "d", "e", "f", "x", "y"]

singleOrDefault

The sequence has more than one element satisfying the condition. I am very sure that my list of strings, which I inspect with break points in webstorm does not contain multiple objects which satisfy the condition.

var type = 'subst';
var filePaths = ['./lib/hangman/wordlists/adv.nor.wordlist.txt',
                 './lib/hangman/wordlists/subst.nor.wordlist.txt']

var path = from(filePaths).singleOrDefault(function(x){ return S(x).contains('/' + type + '.'); });

the error thrown is "The sequence has more than one element satisfying the condition";

var path = from(filePaths).singleOrDefault(function(x){ return x.indexOf(type) !== -1; });

this live gives the same result.

Cannot Re-enumerate

I'm not sure if this is the intended functionality but since lazy evaluation is already in place. The following snippet might be expected to have ['value'] as it's output

var array = [];
var x = from(array);
x.toArray();
//-->[]
array.push('value');
x.data
//-->['value']
x.toArray();
//-->[]
//ideal output of toArray() would reflect x.data

provide umd / amd loader!

so i can include it as a module
