nvm: Execute a script in a specific version of Node.js.

$ nvm exec ${node_version} node ${app-js}

try on your machine

This command is using the nvm (Node Version Manager) tool to execute a specific version of Node.js in a specific JavaScript file.

Here is the breakdown of each part:

nvm exec: This tells nvm to execute a specific command using the selected Node.js version.
${node_version}: This is a placeholder that should be replaced with the desired Node.js version number. For example, if you want to use Node.js version 12, you would replace ${node_version} with 12.
node: This specifies the command to be executed, which in this case is the Node.js runtime.
${app-js}: This is a placeholder that should be replaced with the path to the JavaScript file you want to execute. For example, if your JavaScript file is named app.js and is located in the current directory, you would replace ${app-js} with app.js.

Overall, this command is used to execute a specific version of Node.js on a specific JavaScript file using the nvm tool.
