JavaScript

JavaScript (JS) is what we use when developing our user interfaces. For example, you can find in https://github.com/openmrs/openmrs-core, we use JS to make the OpenMRS installation wizard dynamic.  You can find some more in https://github.com/openmrs/openmrs-module-legacyui, where the older OpenMRS user interface is built in JavaScript.

React

ReactJS is a popular Javascript framework (out of many out there) and it is one of the frameworks used by some of our Open Web Apps in OpenMRS and also http://bahmni.org/. Make sure to that the module/project you will be working on is using ReactJS (and or Redux) before diving into these tutorials because it might also use another JS framework.
