The command "nest build ${project_name}" is specific to the Nest.js framework, which is a JavaScript framework for building efficient and scalable server-side applications.
This command is used to build a Nest.js project, where "${project_name}" is a placeholder that should be replaced with the actual name of your project.
When you execute the "nest build" command followed by the project name, it compiles the TypeScript code of your Nest.js project into JavaScript code, which can be run by the Node.js runtime. This compilation step is required as Nest.js projects are written in TypeScript, which is a superset of JavaScript.
The "nest build" command also performs additional tasks such as bundling the project's dependencies, optimizing the output, and generating the necessary files for running the application. Once the build process is complete, you should have a ready-to-run JavaScript version of your Nest.js project.
It's worth mentioning that before executing the "nest build" command, you may need to install the necessary dependencies for your project using the "npm install" or "yarn install" command, depending on your package manager preference.
