# Speedometer 3.0: TodoMVC: JavaScript Es5 ## Description This application uses JavaScript with ES5 language features to implement a todo application. JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it.. [JavaScript - developer.mozilla.org](http://developer.mozilla.org/en-US/docs/JavaScript) ## Implementation details This implementation uses an explicit MVC pattern, with a clear file structure to reflect the architecture. The storage solution uses an in-memory data object that implements a simple array to hold the todos. ## Built steps A simple build script copies all necessary files to a `dist` folder. It does not rely on compilers or transpilers and serves raw html, css and js files to the user. ``` npm run build ``` ## Requirements The only requirement is an installation of Node, to be able to install dependencies and run scripts to serve a local server. ``` * Node (min version: 18.13.0) * NPM (min version: 8.19.3) ``` ## Local preview ``` terminal: 1. npm install 2. npm run dev browser: 1. http://localhost:7001/ ```
