Can you name popular frameworks and libraries used in frontend user interface development?

Popular frameworks and libraries for developing user interfaces on the frontend include:

• React — a library from Facebook for building UI based on components.
• Angular — a framework from Google that provides a full set of tools for SPA.
• Vue.js — a progressive framework, convenient for gradual adoption.
• Svelte — a modern compiled framework that minimizes runtime.
• jQuery — a library for simplifying DOM manipulation, although now used less frequently.

Example of a simple React component:

function HelloWorld() {
  return <h1>Hello, world!</h1>;
}
