# The Core of JavaScript --- %[https://youtu.be/l4sgVEKsWyk] --- *JavaScript* is a popular programming language used both in the browser and server. It was initially called **LiveScript** but later changed to JavaScript. The programs in the language are called **script**. > JavaScript is a high-level, dynamic, untyped, and interpreted programming language. > It was created in 10 days by Brendan Eich. 😮 It is named JavaScript to position it as a younger brother to Java because Java was more popular back then (in 1995). But they are independent of each other. JavaScript was changed to ECMAScript or ECMA-262 in 1996 but is still called JavaScript. It is executed on any device that has a special program called JavaScript engine or **ECMAScript engine**. The engine renders web pages to the **DOM** (**Document Object Model**) for easier interaction between the browser and the user. The engine is also called **JavaScript Virtual Machine** because it executes code in an environment independent of the platform. > ECMAScript is the standardized [specification of JavaScript](https://www.ecma-international.org/publications/standards/Ecma-262.htm). It contains the most in-depth detailed information about JavaScript. There are different JavaScript engine code names based on the browser. For example, in Chrome and Opera, it is V8; in Firefox, it's Spider Monkey; in Internet Explorer, it's Chakra; in Microsoft Edge, it's ChakraCore; in Safari, it's Nitro and SquirrelFish, etc. The full integration of JavaScript with HTML and CSS makes JavaScript a unique Programming Language. It also supports all major browsers. --- [![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1613668162316/G1zfmhxQd.png)](https://www.cssigniter.com/members/aff/go/belloosagienoah) --- ### Applications of JavaScript - It allows users to interact with web pages. - It is used to build web, mobile, and desktop apps. - It is used to build games on the web. - And many more... %[https://youtu.be/GxouWy-ZE80] %[https://www.youtube.com/watch?v=Sh6lK57Cuk4] **Happy Coding!!!** --- [![Buy me a Coffee](https://res.cloudinary.com/bizstak/image/upload/v1610317510/ko-fi-trans_fr3su4.png)](https://www.buymeacoffee.com/techstackmedia) --- ### TechStack | Bluehost - Get a website with a free domain name for 1st year and a free **SSL** certificate. - 1-click WordPress install and 24/7 support. - Starting at $3.95/month. - 30-Day Money-Back Guarantee.
