**Introduction:**
JavaScript, often abbreviated as JS, has revolutionized web development by providing interactivity and dynamism to websites. In this article, we will delve into the brief history of JavaScript, highlighting its major versions and key features. From its humble beginnings to its current widespread usage, JavaScript has become an indispensable tool for modern web development.

1. Origins and Early Development:
JavaScript was created by Brendan Eich, a Netscape Communications Corporation programmer, in just ten days in May 1995. Originally known as "Mocha," it was later renamed to "LiveScript" and finally settled on "JavaScript" to align with the popularity of Java at that time. The first version of JavaScript debuted in Netscape Navigator 2.0.

2. ECMAScript Standardization:
To ensure JavaScript's standardization and compatibility across different platforms, the European Computer Manufacturers Association (ECMA) established the ECMAScript standard. ECMAScript is the official name for the standardized version of JavaScript.

3. JavaScript Versions:
Let's take a look at the major versions of JavaScript:

   a. ECMAScript 1 (ES1):
      - Released in June 1997.
      - Introduced basic JavaScript syntax, control structures, and objects.

   b. ECMAScript 2 (ES2):
      - Released in June 1998.
      - Focused on bug fixes and minor improvements.

   c. ECMAScript 3 (ES3):
      - Released in December 1999.
      - Introduced significant enhancements, including regular expressions, try-catch exception handling, and more advanced object manipulation.

   d. ECMAScript 4 (ES4):
      - Proposed but abandoned due to disagreements within the community.

   e. ECMAScript 5 (ES5):
      - Released in December 2009.
      - Added features such as strict mode, JSON support, native array manipulation methods, and more.

   f. ECMAScript 6 (ES6) / ECMAScript 2015:
      - Released in June 2015.
      - Brought major improvements, including arrow functions, classes, modules, template literals, enhanced object literals, and promises.

   g. ECMAScript 2016 (ES2016) and onwards:
      - Starting from ES2016, JavaScript switched to an annual release cycle.
      - Each subsequent version introduced new features and enhancements, such as async/await, spread syntax, destructuring assignment, improved array manipulation methods, and more.

4. Modern JavaScript:
Modern JavaScript, often referred to as ES6+ or ESNext, encompasses all the versions released after ECMAScript 2015. It includes ES2016, ES2017, ES2018, and so on. This rapid evolution has brought numerous advancements and made JavaScript more powerful, expressive, and efficient.

5. JavaScript Frameworks and Libraries:
JavaScript's popularity has spawned a vast ecosystem of frameworks and libraries, enabling developers to build complex and scalable applications easily. Some notable frameworks include React.js, Angular, and Vue.js, while libraries like jQuery and Lodash offer convenient utilities for DOM manipulation and data manipulation, respectively.

**Conclusion:**
JavaScript has come a long way since its inception, evolving into a versatile language that empowers web developers to create dynamic and interactive web experiences. From its early days to the latest ECMAScript standards, JavaScript has continued to grow and adapt to the changing needs of the web. As we move forward, JavaScript will undoubtedly play a pivotal role in shaping the future of web development.
