How to get formatted console message in Google Chrome's developer tools?

Question

Today I were surprised of getting a formatted console message while surfing on Facebook.

I have no need to use formatted console messages but I am wondering how to get formatted console messages? Just a chrome feature?

I'm using Google Chrome on my Macbook.

Answer 1

console.log("%cThis will be formatted with large, blue text", "color: blue; font-size: x-large");
