JS HashSet A rapily searchable inplementation of hashsets for js and node development.
A HashSet is like an array, in that it holds multiple values / objects. It stores these values such that it is very easy and fast determine whether an value is existent in the set already.
Hashsets are popular in dotNet and Java applications as a very fast way for looking up (searching)the existance of a value in a dynamic data set.
HashSets excel when you are consistent (iterative) checking an array for the existence of an item. By replacing the array with a hahsset, search performance can be rapidly reduced. The larger the data set, the bigger the improvement.
Close to universal JS compatability on modern platforms.
JS HashSets has been tested for datasets from 1-100000 items compared to a normal linear js array.
JS HashSet is open source software with a permissive BSD license. You can use it in both free and commercial project for free, and can modify and update the code in agreement with the simple, plain english license terms. Download JS HashSet.
