node: Evaluate JavaScript code by passing it as an argument.
$ 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 "${code}"
: This is an argument passed to thenode
command. The-e
flag tells Node.js to execute the following command-line argument as JavaScript code.${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.

never run a command you are not sure if it is safe.
