d8:tldr:8c5ed

The command "d8 -e "${code}" is used to execute JavaScript code using the d8 command-line tool.

Here's a breakdown of each part of the command:

• "d8": This is the name of the command-line tool. "d8" stands for "Developer's Edition," and it is a command-line JavaScript shell provided by the V8 JavaScript engine, which is primarily used in Google Chrome.
• "-e": This option is used to specify code to be executed directly from the command-line instead of reading it from a file.
• "${code}": This is a placeholder that represents the actual JavaScript code you want to execute. The code should be wrapped in double quotes. The "${code}" will be replaced with your actual JavaScript code when you run the command.

For example, if you want to execute the JavaScript code "console.log('Hello, world!');", you would replace "${code}" with the actual code like this:

d8 -e "console.log('Hello, world!');"

The command will execute the specified JavaScript code using the d8 shell and display the output, if any, in the terminal.
