I’m looking at some of the Forms we built using HubSpot, and I’ve noticed they all include data attributes like ‘data-reactid=“.hbspt-forms-0”’. There’s also a JavaScript file imported from “/\_hcms/forms/v2.js” that uses a lot of React functions:

Does HubSpot use the React framework alongside JQuery? If so, why do we need two frameworks? Wouldn’t it be more efficient to build a CMS with only one? My [React Dev Tools plugin](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en) says it’s using an “older unsuported version” of React.

Hi @marquizzo, I’m not using React on HubSpot but if you check their documentation you can see it’s in BETA so not everything might be working as expected: [How to use JavaScript frameworks on HubSpot - HubSpot docs](https://developers.hubspot.com/docs/cms/guides/js-frameworks#reactjs)  
You can provide your feedback directly to the GitHub repository if you want 🙂

Hi @marquizzo,

yes - HubSpot is build upon React but only for several years. There were times were HubSpot wasn’t build on react - and tbh I don’t know what was before that. I remember that the interface was using the most basic jQueryUi styling when I’ve started with HubSpot years back.

And since there are still functions requiring jQuery - it’s getting loaded.

But HubSpot constantly improving everything and I’d say that there will be a day when jQuery will disappear from HubSpot(not the themes)

best,

Anton
