Rust and Leptos Training Overview
Rust is an excellent language for building front-end web applications with WebAssembly. Leptos is a component-based front-end web framework similar to React, Angular, and Solid.js. In this Rust training course, attendees learn how to build front-end web applications with Rust and Leptos. Participants learn how to create components, pass data to components, and emit events from components. By the end of this course, students confidently build front-end web applications with Rust and Leptos.
