Visual Studio Code (referred to as VS Code) is a free, open-source code editor developed by Microsoft. It supports multiple programming languages and provides features like syntax highlighting, intelligent code completion, code refactoring, and debugging. Visual Studio Code has built-in support for Vue.js's core building blocks: HTML, CSS, and JavaScript. VS Code includes a built-in terminal, allowing you to run command-line tools like npm and yarn directly within the editor, facilitating project building and management. If you desire a richer Vue.js development environment, you can install the Volar and Volar for TypeScript extensions. These extensions provide intelligent hints for Vue.js. > If you are not familiar with VS Code or haven't installed it yet, you can refer to: (#). * * * ## Create a Vue Project Open a terminal or command prompt and enter the following command: npm create vue@latest You will be prompted to enter a project name.
