What is JavaScript (JS)?

JavaScript (JS) is a programming language interpreted as the dialect of the ECMAScript standard and is defined as object-oriented, prototype-based, mandatory, poorly written, and dynamically.

What is the JavaScript Programming Language?

Netscape and Sun Microsystems, the creator of the Java language, re-introduced it in Javascript in December 1995 to co-develop the project.

In response to the popularity of Javascript, Microsoft released VBScript, a small structure of its script-based programming language VisualBasic.

In 1996, Microsoft launched the Jscript language introduced in the Internet Explorer web browser to compete with Javascript.

Javascript was developed to help website authors create and edit specific pages for users to create more complex websites.

HTML allowed to create static pages that could only display text, but one-to-one interaction was required with users.

In the 1990s, Netscape created and released LiveScript. The earliest versions of the LiveScript language were intended primarily for small groups of web designers who do not need to use a compiler or have object-oriented programming experience.

As new versions of this language became available, they included new components that gave the language great potential, but unfortunately, this version only worked on the latest version of Netscape Navigator at that time.

JavaScript was originally developed under the name Mocha, which was later renamed LiveScript by Brendan Eich by Netscape, and eventually, its name was changed to JavaScript.

When Netscape added support for Java technology in the Navigator web browser in version 2.0B3, the name change caused a conflict.

JavaScript created the confusion that it is an extension of Java and interpreted by many as a marketing strategy by Netscape to gain prestige and innovate in new web programming languages.

JavaScript Features

Since you don’t need advanced programming knowledge to learn how to use JavaScript, this programming language is recommended by many experts when you research a language to start programming.

By processing the objects on our website, we can define different events on the objects.

These objects make it easier to program and design interactive pages, while preventing the execution of commands that may be dangerous to the user’s machine, such as formatting the drivers, replacing files.

Because it has a dynamic structure, it can respond to real-time events such as pressing a button, hovering over certain text or just loading the page.

Instead of storing pages or pages on the webserver for each user, we can leave the appearance of the pages entirely under the control of the user by making calculations based on the variables determined by the user.

There are many programming languages ​​such as Vue or React, which are used in various fields based on JS.

   Differences Between Java and Javascript

1) Compiler

To program in Java, we need a Development Kit and a compiler. In contrast, the page is interpreted by the browser because there is no language that requires your Javascript programs to be compiled.

2) Object-Oriented

Java is an object-oriented programming language, but it is not Javascript. This means that we can program without creating classes, as done in structured programming languages ​​such as C or Pascal.

3) Purpose

Java is much more powerful than Javascript because it is a general-purpose language that you can do a wide variety of applications.

With Javascript, we can only write programs that will work on web pages, but technologies were introduced that allow the scope of JavaScript to be extended to other areas, such as video game programming or writing common desktop programs.

As you can see, Java is a much more complex but also strong, robust, and reliable programming language.

It has more functionality than Javascript, and the differences that distinguish them are easily distinguishable.

Usage

Although it is a server-side JavaScript format, it is mainly used in the client-side format, which is implemented as part of a web browser that allows improvements to the user interface and dynamic web pages.

Although JavaScript is similar to the name of the Java programming language, it is designed with a syntax similar to C. However, Java and JavaScript are not interrelated and have different semantics and purposes.

Among the different services offered with Javascript on the Internet, mail services, IRC/chat, hours, visit counters, date, account, form, browser, and language detectors can be counted.

Website Code Structure

Javascript code is included in the <body> </body> tags of web pages. These codes are usually added between <script> </script> and can also be found in external JS files.

Example: <script src="font.js">  </script>

Browser Compatibility

Javascript is supported by most web browsers such as Internet Explorer, Opera, Google Chrome, or Mozilla Firefox.

Ajax for XML was developed with the emergence of languages ​​such as PHP on the server-side and Javascript on the client-side.

This language combines various technologies such as HTML and CSS to create interactive web applications.

XMLHttpRequest is one of the most important functions it contains, which allows data to be synchronized asynchronously with the webserver.

Although the JS language is supported by many web browsers, you can disable or enable it in the browser settings.

It is recommended to include JS files as an external file due to both accessibility, browsing practicality, and page speed.
