Question

Creates a new sequence comprising the elements from the head of this sequence that satisfy some predicate. Once an element is encountered that doesn't satisfy the predicate, iteration will stop.

Signature

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

Sequence.takeWhile = function takeWhile(predicate) {
  return new TakeWhileSequence(this, predicate);
}

Name	Type(s)	Description
predicate	Function
returns	Sequence	The new sequence

Examples

function lessThan(x) {
  return function(y) {
return y < x;
  };
}

Lazy([1, 2, 3, 4]).takeWhile(lessThan(3)) // sequence: [1, 2]
Lazy([1, 2, 3, 4]).takeWhile(lessThan(0)) // sequence: []
