Dot Syntax

What is the meaning of the dot?
The dot signifies that we want to use something that’s inside something else.

console.log("log is inside of a console");

myObject.search("Tony de Araujo");
// search is a method which is inside of object myObject

Hope it helps!

Styling JavaScript Console.log

Did you know we can style the output from a console.log on a modern JavaScript Console?
It may not be something to do all the time but for that particular occasion where it will make a difference here it is the recipe:

console.log("%cHello World!", "color: red; font-family: Verdana");

It outputs Hello World!

What about a multicolor output?

console.log("%cHello %cWorld!", "color: red; font-family: Verdana","color: blue; font-style: italic");

It outputs Hello World!

The secrete is in the %c which serves as a placeholder for the style that follows as the second or third arguments.
