what this signifies <%@ taglib prefix="c" uri="jakarta.tags.core" %> in jsp file under src root folder src/webapp/WEB-INF/jsp/home.jsp?

Question

I'm following a video where tutor added the above line to see result on jsp from controller after writing model.addAttribute("", ); and mentioned JSTL tags and jasper for rendering in dependency file. He also changed form @restcontroller to @controller to pick the home.jsp file.

I just wanted to know the purpose of above line and how it helps.
