We decided to help; so in this article, we are going to dig deep into how does JavaScript work? And the best way to learn JavaScript.

and as we are a Web Development Company we recommend that JavaScript be a priority to learn

What is JavaScript?

Simply; JavaScript is a web scripting language, which its code can run directly in a web browser, without the need for a compiler to translate it.

JavaScript has the ability to work with CSS and HTML, so you can get the ability to build web pages or even web apps. It also can work even on web servers. 

Today; JavaScript is supported by most modern web browsers, so it is common and unique and supported by most new mobile phones too. 

How does web programming work?

Before telling you how does JavaScript work, you should know first how web programming works?

We can build a website or a mobile app with the help of the three following elements:

1- HTML:

HTML stands for Hypertext Markup Language. HTML is the main element that displays the content on the website because all the images, titles, texts, and sections are written in HTML language.

2- CSS:

CSS stands for: Cascading Style Sheets and It controls the style and layouts. 

CSS transforms the plain text into the colorful designs you see on a website. It creates fonts, colors, borders, etc.

3- JavaScript:

Now it is the JavaScript turn. The dynamic elements you can see on the website came from the role of JavaScript. It controls media, authenticates password forms, etc.

The three elements work together in amazing harmony, so you can see the websites this way.

How does JavaScript work?

The best way to learn JavaScript is to start learning how it works.

There are two important elements you should learn about to better understand JavaScript, they are:

• The DOM or Document Object Model. 
• The way a web browser works. 

The Web browser creates the DOM and parses the HTML, then your browser will bring every element related to the HTML language. 

The CSS parser will bring the needed data and work together with the HTML, so they can create the web page.

Then comes the turn of JavaScript to show its elements, after the full loading of HTML and CSS.  

The best way to learn JavaScript is one of the following:  

• Self-Guided Websites.Books.
• Events.
• The coding boot camps.
