Question

Checks whether every element in this sequence satisfies a given predicate.

Signature

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

Sequence.every = function every(predicate) {
  predicate = createCallback(predicate);

  return this.each(function(e, i) {
return !!predicate(e, i);
  });
}

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 every element in the sequence (or the sequence is empty). False if predicate returns false for at least one element.

Examples

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

var objects = [{ foo: true }, { foo: false, bar: true }];

Lazy(numbers).every(isEven)     // => false
Lazy(numbers).every(isPositive) // => true
Lazy(objects).all('foo')        // => false
Lazy(objects).all('bar')        // => false
