Which architecture designs for the front-end / Javascript? [closed]

My question: I'm a student building a simple website. I have done MVC architecture with Java and Spring Boot backend, My front-end is (HTML/CSS/Javascript). What architecture is good for structuring the frontend (mainly javascript wise)?

Because I have read that MVC suits backend but is too outdated for the front-end, and front-end should use unidirectional architecture like FLUX or REDUX (which I haven't really looked much into because I don't want to dig in to frameworks and libraries like React and Angular). I apologise in advance if I'm speaking gibberish or if my question actually makes sense.
