Hello World

As usual the first thing to do when you are beginning a new language : Hello World !

Why Hello World ? ๐Ÿ˜‰

In JS they are multiple different ways to do that :

  • Using alert box
  • Using the console
  • Modifying the DOM ...

I coded for you few examples, feel free to do the same thing on your computer, you just need a text editor and a web browser to open your HTML file ๐Ÿ‘Š

Code

Explanations

alert() method will open an alert box when the page is loaded containing the string that you passed in

console.log() method is logging your string as a message in the console

console.warn() method is logging your string as a warning in the console

document.querySelector("#id") is returning the DOM element with ID, and textContent will help to add text to this element

๐Ÿš€ In our next post you can see how to declare variables in JavaScript
