Perfect! At Systra (and in general in the world), the front-end development is made using JavaScript. Plenty of tools can assist us in our development. Times when you could develop only by using CSS/HTML and a little bit of 'raw' javascript are behind us.
At Systra, we can develop our frontend applications by using either Vue or React:

Both frameworks:
- Are reactive
- Work with reusable components
- Have a wide community
- Are quite easy to take in hand
Are you more familiar with React or with Vue?
To help you decide, you can find some interesting data gathered by users (like satisfaction, appreciation, interest...) about the various frontend frameworks here.
