Brandan Eich, a Netscape programmer, developed a new script language in just 10 days. It was originally called Mocha, but quickly became known as Livescript and Javascript.
There is a question about why is called Javascript. Does it have something to do with Java? Do you want to impress your friends and family with your knowledge of the etymology of the name JavaScript? If you really want to become a real expert, you can take a class with us.
What is JavaScript in simple word?
is a programming language used on the Web. It is used to enhance the look and feel of the pages. is a language that is interpreted. Thus, it does not need to be compiled. The web pages are rendered in an interactive and dynamic fashion with the help of javascript.
This allows the pages to react to events, exhibit special effects, accept variable text, validate data, create cookies, detect a user is browser and many other things. The majority of pages nowadays are not static. Menus, forms, slideshows and even images provide user interaction on many of the pages today.
The language used by web developers to provide such interaction is javascript. To harness the full potential of Javascript, a developer needs to know the ins and outs of the scripting language. There are other languages that can be used for script on the Web, but in practice it is all Javascript.
Good old HTML and CSS are what most people start with when they start learning to code. They move on to after that. Which makes sense, right? There are three elements that make up the core of web development. I mentioned that is a programming language.
is a script language that many browsers use to do dynamic things on the web

What is JavaScript code called by using?
The code is sent to the web browser in its original text form and it runs the script from that. When a web page is viewed, the page is client-side code that is downloaded, then run and displayed by the browser.
What is even more exciting is that the client-side language has been built on top of. There are so-called Application Programming Interfaces that give you more power in your code.
is used to create web pages and mobile applications. It's one of the building blocks of Brendan Eich and it's one of the things the bosses wanted to have. They thought that would help speed up web development and be easier to learn compared to java.
can be used to modify a user interface via the Document Object Model, as mentioned above. If is loaded and run before the HTML and CSS that it is intended to modify, there could be errors.
Your code won't work if the is loaded before the HTML you are attempting to do something to. The code will work if both the script and the text are loaded at the same time.

What are the parts of a JavaScript code?
A broken program console.log is an example of a broken program console.log.
The first part of this series will show how our code is executed. You might be wondering why this is important. Well, if you want to know how the function call and global environment work. Every time a piece of code is run in JavaScript, it is in an execution context.

What is the JavaScript code called?
The browser has an embedded engine sometimes called a "JavaScript virtual machine" that can execute on the server or on any device that has a special program.
In this article, we talk about the differences between Java and Javascript. We will show you an overview of some of the more significant functions. is the most simply put.
Many ideas are borrowed from the Java language, which is the reason why is named after it. Java and are two completely different languages. The most significant difference between them is that Java is compiled and is interpreted.
runs on many browsers out of the box, whereas Java applets require an additional plug in. There are different governing bodies and different libraries for both languages. is a very useful language despite it's many flaws. Every web browser has running in it.
A application runs on every device, whereas a desktop or mobile application only runs on the application it is targeted to (Windows, Mac, Linux, iPhone, Android). You can write cross- platform apps in a really easy way thanks to this. The role of has expanded significantly.
There are platforms that allow developers to run on a server. It is now possible to create entire web applications in which both client-side and server-side logic is written in JavaScript.
