Something you may not know about console log in JavaScript

The normal stuff

The basics for the console.log() in JavaScript is just this:

console.log("Hello World!");

But did you know that you can stylize the text you are logging? To add styles to the text you just need to add %c to the beginning of the text that you want to style. For an example of this in action, this is the welcome message for Developer Bacon.

console.log(
    "%cWelcome to the console of developer bacon",
    "color:pink;text-transform:uppercase;font-weight:bold;"
);

Adding more styles

To add more styles to other text in the same console log you need to add the %c just before the second group of text. You can add as many of these indicators as you want you just need to add a new style group for each text group. Here is an example of multiple styling groups in action.

console.log(
    "%cThis text will be bold. %cThis text will be red. %c This text will be small",
    "font-weight:bold;",
    "color:red;",
    "font-size:8pt"
);
