front end tool for page creation to add to asp.net application

Hi,
We have existing ASP.NET (not core) application. My colleague added a page to this using jquery, knockout and checkeditor and talking to back end database and saving data.

Similar requirement came up for me to add another page. But my page needs user interaction like they should be give freedom to add images or videos and I should save entire page content to database. It’s like revisions of updates. When ever user want to see historical update, should provide links and clicking on it, should load that version of content including css or design.

I need your suggestion for how to achieve this and add to existing asp.net application.
Is React better or knock out or jquery. Please let me know along with tool names. I am new to front end development.

Thanks,
Spunny
