NodeJS simple horizontal line on console.log - node.js

Question

I'm making a simple Node JS app.
It logs a lots of informations on console. I would like to know if it's possible to add a horizontal lines in Node JS command line without using any extra packages or dependencies.
If command prompt supports HTML elements, then I could use something like console.log("<hr>"); for adding a horizontal line but it does not support HTML.
Is there any way ?

Answer 1

To create the string for the horizontal line:
const line = '-'.repeat(process.stdout.columns)
.repeat() method repeats the string.
process.stdout.columns returns the number of columns.
To use it:
console.log(line)

Answer 2

The console does not support rendering HTML elements.
That does not prevent you from making a custom line however!
const lineBreak = '----------------------'
console.log(lineBreak)
Of course, customize the linebreak however you'd like:
______ //Underscores!
----- //Hyphens!
====== //Equals!
For grouping related data, refer to the docs here: console reference
Example:
function name(obj) {
console.group('name');
console.log('first: ', obj.first);
console.log('middle: ', obj.middle);
console.log('last: ', obj.last);
console.groupEnd();
}
name({"first":"Wile","middle":"E","last":"Coyote"});
Will output grouped data to the console, visually giving it a line break & arrow to collapse the group. I think this would work well for your use case.

Working off on the same vane as #sergey above:
If your output has a header of a determinable length you can use the .length method.
const header="This is my header";
console.log(header);
console.log('-'.repeat(header.length);
