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