disect

node-disect

Bisection helper for javascript

Installation

npm install --save disect

Usage

Disect helps you find the first item in a list to satisfy a predicate, nothing more.

disect(0, 100, function (index) {
  return index >= 56;
})
// returns 56


// or with an array
disect([10, 20, 30], function(element, index) {
  return element > 11;
})
// returns 20;

// if you're into that...
Array.disect = function(predicate) {
  return disect(this, predicate);
}

Reference

new CatStream([transformer], [options])

bisect(min, max, predicate)

Process a bisection on indexes ranging from min to max (max not included) returning the first that satisfies the predicate. This means that all indices superior to the one returned MUST validate the predicate as well.

• min - Number: the minimum index against which to test
• max - Number: no indices will be tested that are equal or greater than this
• predicate - Function(index): A callback to call to test the index.

bisect(array, predicate)

Same as above, except min and max are mapped to 0 and array.length. The predicates' signature differs.

• array - Array: The array containing the elements to iterate on
• predicate - Function(element, index): A callback to call to test the element of the array at the given index
