node: Evaluate JavaScript code by passing it as an argument.

node

$ node -e "${code}"

try on your machine

The command node -e "${code}" is used to execute a JavaScript code snippet directly from the command line using Node.js.

Here's a breakdown of its components:

node: It invokes the Node.js runtime environment, which allows you to execute JavaScript code outside of a web browser.
-e "${code}": This is an argument passed to the node command. The -e flag tells Node.js to execute the following command-line argument as JavaScript code.
- ${code} is a placeholder that represents the actual JavaScript code you want to execute. It should be enclosed within double quotes ("") to ensure the entire code snippet is passed as a single argument.

By using this command, you can quickly execute short snippets of JavaScript without creating a separate JavaScript file.
