Structure.js is a JavaScript library of useful data structures.

Early stages of development. Currently contains only a hash table. Stay tuned for more.

Install it using npm:

npm install structure.js

or add structure.js as a dependency to your package.json file.

Then you import the module through require('structure.js'), as usual.

Add a script tag with the lib/structure.min.js file. It will define the structure property on window.

You can use lib/inline-* to inline the code into some file using grunt or a similar tool. The code will define the structure object and populate it with the data structures (for example, if you inline lib/inline-hashtable.js, you'll get structure.HashTable).

To get the code into your project in the first place, you'll probably want to use npm like above.

This is not your Java HashMap - you certainly don't want to use it "everywhere". However, if you need to preserve a large number of mappings for keys other than strings and numbers, this will be a lot faster than keeping two parallel arrays and doing linear searches. For specific rule-of-thumb numbers, try it out or wait for the benchmarking numbers.

Structure.js is being developed by Ivan Budiselic with contrubitions from Ivan Zuzak.
