It has the largest library ecosystem of any programming language. Since it is a scripting language, its code can also be written on an HTML page.

So when a user requests an HTML page in which JavaScript is present, then this script is sent to the browser and it depends on the browser what it wants to do with it.

By the way, JavaScript does not have any relation with Java. JavaScript is called simply because of the use of Java in its name: The World’s Most Misunderstood Programming Language (the world’s most misunderstood language)

JavaScript Official Name is ECMAScript defined under Standard ECMA-262.

What are the Frameworks of JavaScript?

Frameworks that are used most frequently are React JS, Angular JS, Create JS, jQuery, nodeJS, etc.

Introduction to Javascript

JavaScript is one of those 3 languages that all web developers must learn, let’s also know about those three languages.

  1. HTML is used to define the content of web pages.
  2. CSS is used to specify the layout of web pages.
  3. JavaScript is used to program the behavior of web pages. Web pages are not the only place where JavaScript is used. JavaScript is also used in many desktop and server programs.

Node.js is such a program. In some databases, such as MongoDB and CouchDB, JavaScript is used according to their programming language.

Difference Between Java and Javascript

Often people think that the difference between Java and JavaScript is the same. But in reality, it is nothing like that. So let us know about the difference between these two.

  • What is Java and how to learn
  • What is IP Address
  • What is a web browser

JavaScript is not the same as Java at all. I want to tell you one more time that both JavaScript and Java are different.

By the way, the names of these two are very similar, which create doubt in the mind of the people. Where this language is primarily used as a scripting language in HTML pages, Java is a real programming language that is used entirely in other tasks.

Whereas learning Java can be a bit difficult. It was developed by Sun Microsystem for use in all those things where computing power was needed.

JavaScript was developed by Brendan Eich, who worked at Netscape at the time, and developed as a client-side scripting language (although there is no fundamental reason why it should be used in a server-side environment). cannot be used).

Originally the name of this language was Live Script, but when it was about to be released, Java had become very popular. That’s why Netscape changed its name to “JavaScript” at the last possible moment.

Both Java and JavaScript are descendants of C and C++, but these languages ​​work completely differently from their ancestors. Both languages ​​are object-oriented, yes and they also share some similar syntax. But there are more differences than similarities.

Advantages and Disadvantages of JavaScript in English

Like other computer languages, JavaScript also has some advantages and disadvantages. Where earlier it was limited to doing only a few tasks, nowadays it is used in many tasks.

Advantages of Javascript

  • Speed. Client-side JavaScript is very fast because it runs immediately in the client-side browser. As long as external resources are needed, JavaScript is completely unhindered from network calls to a backend server.
  • There is no need for it to be compiled on the client side so that it gets some speed advantages.
  • Simplicity. JavaScript is very simple to learn as well as to implement.
  • Popularity. JavaScript is used throughout the web. Along with this, there are many resources on the internet to learn it as well. StackOverflow and GitHub are two great websites from where you can learn everything about Javascript.
  • Interoperability. JavaScript is easily compatible with other languages, along with it is also used in many applications. Unlike PHP and SSI scripts, JavaScript can be easily inserted into any web page.
  • JavaScript can also be used within other scripts that have been written in different languages ​​such as Perl and PHP.
  • Server load. Due to its use on the client side, its demand in the website server decreases.
  • Rich interfaces. Having drag, or drop components or sliders, provides a rich interface to your website.
  • Versatility. Now JavaScript is also being used on many servers. JavaScript is used in the client’s server in the front-end, as well as now a complete JavaScript app can also be created from front to back with the help of JavaScript only.

Disadvantages of javascript

  • Client-Side Security. Since this code is executed from the user’s computer, so in some cases it can also be exploited for malicious purposes. This is one of the main reasons why some people prefer to disable Javascript.
  • Browser Support. JavaScript is sometimes interpreted differently in different browsers. While server-side scripts always produce the same type of output, the output of client-side scripts is a bit unpredictable.
  • Well, this is not a big problem because as long as they are working properly in big and popular browsers, then everything is safe.

Today’s Javascript

Talking about the present time, then these scripts are available everywhere – it is the most commonly used client-side scripting language. JavaScript is written in HTML documents and it enables interactions with other web pages in very unique ways.

For example, it is only because of JavaScript that I can automatically schedule appointments and play games online. In addition, new developments, such as Node.js, allow it to be used server-side while APIs, such as HTML5, allows control of user media and other device features.
