JavaScript

This language is one of the most famous coding languages among technology engineers. It assists web developers in making a website that interacts with the users. A website provides a two-way communication method. Back then, a website was usually static or worked in a one-way manner. In this regard, such a website was just displaying information, and thus, its users did not want to explore more.

Currently, almost all websites offer great experiences. Thanks to JavaScript, programmers can create videos, quizzes, registration forms, and even animations. All of these factors make users spend more time on the websites, play with the quizzes, and take part in the events. Their experiences are more impressive. Find out more about the language in the paragraphs that follow.

What is JavaScript?

JavaScript is a programming language that helps create an Internet site with various content that emerges automatically. Its users will not need to load the content or the web pages manually. Such a strategy makes it engaging for the users to find out more about what the website has to offer them.

For web developers, JavaScript is necessary for understanding the behaviours of users when exploring a website. They will get information on what web features or topics the visitors love the most. Such information will benefit them in upgrading the existing website or making it a more interactive one.

This useful system was developed by Brendan Eich in 1995. He created the language when his company, Netscape Communications, asked for his idea to create one that would run in the Netscape Navigator browser. Now, programmers rely on the source code to make various software products, from simple Internet sites to games, which are engaging and useful. 

JavaScript, CSS, and HTML

JavaScript can not work alone to craft an Internet site that is dynamic and user-friendly. It needs a supporting system like CSS and HTML to make a framework. All of these are necessary for any web programmer to develop a microsite. In this case, HTML stands for Hypertext Markup Language. It helps web engineers to make the structure and content of a web page. 

Mastering HTML is the key to determining how the engineers will display the content to the users. At the same time, Cascading Style Sheets, or CSS, is the code for designing the visual look of a website. It is used to control the colour, size, layout, and other aspects of a web page's appearance.

The Workflow of JavaScript

JavaScript is renowned for being relatively easy to master compared to other code sources. It contains a syntax and code-writing system that is concise and easy to understand. No wonder that many web developers use the source code to make mobile applications. Another plus side of the language lies in its flexibility.

JavaScript is applicable for both the front-end and server sides when using Node.js. It is because the platform provides all frameworks and libraries that already support the language. In terms of the workflow, the coding language undergoes six stages before making responsive features according to the developers' commands. Read them in the brief list below! 

Code writing

The first step is writing the codes, which refer to the instructions from the developers to the computer. The commands can vary from showing messages on the screen to changing web displays. Next, the developers will write the code in the files with .js extensions or inside the <script> tag in HTML files.

Parsing

Parsing means analysing and converting texts or strings, such as JSON or HTML, into understandable formats. This web scripting language later uses the formats to process and manipulate data more effectively. JSON itself is a JavaScript Object Notation, or text-based data format that is light, flexible, and easy for humans or machines to read. It is useful for keeping and exchanging data, particularly in web apps.

Execution 

The next phase is execution, which refers to running every line of the code. During the process, the programmers must note all aspects of the code's performance. If the browser discovers some errors or bugs, it will send a message about them to the console. Hence, the programmers have to fix them right away.

DOM manipulation

DOM stands for Document Object Manipulation. In this phase, the JavaScript language helps programmers to change the display and the content of the web page or HTML. It is time for the developers to make an interactive web page in a shorter time because they do not have to reload the whole page.

Interaction

During this stage, the programmers use the code to allow the web pages to interact with the visitors. Examples of interactive content include pressing certain buttons, filling out some forms, or taking quizzes. When a web visitor clicks a button, the language detects that action and then modifies the web page display, like adding or changing the content according to the user’s needs.

Asynchronous

The last phase refers to supporting the programmers’ actions or operations that take a long time without disturbing their other tasks in executing other code. The actions include taking data from the server, loading images, or running animations. In this case, JavaScript enables developers to carry out tasks without blocking the web pages.
