A quick guide on customJS use cases

Let’s start with the basics, customJS is one of the many options available for calculatorians when making a calculator. The customJS tab consists of a text window where you can write your own (custom) javascript (JS) code to be executed when the calculator is loaded and during subsequent calculations. As a calculatorian you can chose to run plain Javascript code (though it’s functionality is capped) or use some of the omni functions that are at your disposal. The available Omni functions help you interact with the elements of the calculator as well as to run commands at different moments in the loading-calculating process.

In this section we will take a look at when and why we use customJS in our calculators. We will not explain how to this, that is reserved for other sections where we will take a look at the Technical documentation of custom functions, Standard practices in customJS, Tips and Tricks from other calculatorians.
