$3

A collection of functions for processing and formatting data.

Some of these may be redundant, depending on their runtime (e.g. helperFunctions.getTime() in a browser with the Internationalization API). These functions are mostly meant to act as polyfills for runtimes where they are not natively supported.

Many of these functions are extremely simple (e.g. helperFunctions.arrayRandom(arr)), and you may ask yourself why they require a function. The reason is that I do not feel like writing it 200,000 times, or the underlying code isn't nearly as semantic as a named function.
