Answer 1

Quoting MDN Docs here

console — contains many methods that you can call to perform rudimentary debugging tasks, generally focused around logging various values to the browser's Web Console.

By far the most commonly-used method is console.log, which is used to log the current value contained inside a specific variable.

How to use in Javascript?

let myString = 'Hello World';
console.log(myString);

Also remember console is a part of global window object in the web browser. Thus the following is also technically correct but isn't used in practical scenario.

let myString = 'Hello World';
window.console.log(myString);
