Creates a slice of `array` with elements taken from the beginning. Elements
are taken until `predicate` returns falsey. The predicate is invoked with
three arguments: (value, index, array).

@param {Array} array The array to query.
@param {Function} [predicate=_.identity]
The function invoked per iteration.
@returns {Array} Returns the slice of `array`.
@example

var users = [
{ 'user': 'barney',  'active': false },
{ 'user': 'fred',    'active': false},
{ 'user': 'pebbles', 'active': true }
];

_.takeWhile(users, function(o) { return !o.active; });
// => objects for ['barney', 'fred']

// The `_.matches` iteratee shorthand.
_.takeWhile(users, { 'user': 'barney', 'active': false });
// => objects for ['barney']

// The `_.matchesProperty` iteratee shorthand.
_.takeWhile(users, ['active', false]);
// => objects for ['barney', 'fred']

// The `_.property` iteratee shorthand.
_.takeWhile(users, 'active');
// => []
Creates a slice of array with elements taken from the beginning . Elements are taken until predicate returns falsey . The predicate is invoked with three arguments : ( value index array ) .
