Question

Checks whether NO elements in this sequence satisfy the given predicate (the opposite of Sequence#all, basically).

Signature

Sequence.none = function(predicate) { /*...*/ }

Sequence.none = function none(predicate) {
  return !this.any(predicate);
}

Name	Type(s)	Description
predicate	Function?	A function to call on (potentially) every element in this sequence.
returns	boolean	True if predicate does not return true for any element in the sequence. False if predicate returns true for at least one element.

Examples

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

Lazy(numbers).none()           // => false
Lazy(numbers).none(isEven)     // => false
Lazy(numbers).none(isNegative) // => true
Lazy([]).none(isEven)          // => true
Lazy([]).none(isNegative)      // => true
Lazy([]).none()                // => true
