Đây là bài viết đầu tiên trên trang, và sẽ còn được tiếp tục cập nhật. Bài viết bàn về khái niệm Javascript là gì. Vì sao đây là ngôn ngữ đáng học.
JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles.
The standard for JavaScript is ECMAScript. As of 2012, all modern browsers fully support ECMAScript 5.1. Older browsers support at least ECMAScript 3. On June 17, 2015, ECMA International published the sixth major version of ECMAScript, which is officially called ECMAScript 2015, and was initially referred to as ECMAScript 6 or ES6. Since then, ECMAScript standards are on yearly release cycles (cập nhật hàng năm). This documentation refers to the latest draft version, which is currently ECMAScript 2019.
Do not confuse JavaScript with the Java programming language. Both “Java” and “JavaScript” are trademarks or registered trademarks of Oracle in the U.S. and other countries. However, the two programming languages have very different syntax, semantics, and uses.
