Question

Checks whether at least one element in this sequence satisfies a given predicate (or, if no predicate is specified, whether the sequence contains at least one element).

Signature

Sequence.some = function(predicate) { /*...*/ }

Sequence.some = function some(predicate) {
  predicate = createCallback(predicate, true);

  var success = false;
  this.each(function(e) {
if (predicate(e)) {
  success = true;
  return false;
}
  });
  return success;
}

Name	Type(s)	Description
predicate	Function?	A function to call on (potentially) every element in this sequence.
returns	boolean	True if predicate returns true for at least one element in the sequence. False if predicate returns false for every element (or the sequence is empty).

Examples

var numbers = [1, 2, 3, 4, 5];

Lazy(numbers).some()           // => true
Lazy(numbers).some(isEven)     // => true
Lazy(numbers).some(isNegative) // => false
Lazy([]).some()                // => false
