VS Code is a very popular code editor that supports multiple programming languages. Among them, Node.js is a very common server-side JavaScript environment. Running Node.js in VS Code allows us to develop and debug our back-end applications more conveniently. So, how to run Node.js in VS Code? This article will tell you.
1. Install Node.js
The first step is to make sure Node.js is installed. If you already have Node.js installed, you can skip this step. If it is not installed, you can follow the steps below to install Node.js:
