What does computer javascript mean?

In the field of modern technology, JavaScript has become a very important programming language. JavaScript can run on modern browsers to achieve dynamic effects and responsive interactive user interfaces. As a scripting language, it works with Hypertext Markup Language and CSS to easily enrich and optimize the user experience of web pages.

JavaScript was originally developed by Netscape Corporation (now a subsidiary of AOL) and debuted in 1995. Its goal is to make web pages more interactive and real-time. However, in 1996, Microsoft also launched a language similar to JavaScript called JScript. Although the two have many similarities, there are subtle syntax differences.

JavaScript was officially named ECMAScript by the ECMA International Organization in 2005. This is the official name of the language and its standardized name. The relationship between JavaScript and ECMAScript is similar to the relationship between Java and the Java virtual machine. Java runs as compiled code, while ECMAScript is an interpreted language that needs to be interpreted and executed inside the browser.

As a high-level scripting language, JavaScript can run independently on the client side of modern browsers and can interact with HTML and CSS. JavaScript can be used to implement a variety of functions, including dynamic images, client-side validation, form processing, animation effects, mobile device development, database operations, game development, and more.

In the modern IT industry, front-end technology has attracted more and more attention, mainly due to the power and flexibility of JavaScript. JavaScript is an essential skill for front-end development. Based on HTML and CSS, JavaScript can make web pages more vivid, real-time, and interactive, making the entire user experience more complete.

In addition, with the emergence of the new Node.js platform, JavaScript has also begun to be used for back-end development. This can make up for JavaScript's shortcomings in IO operations on the one hand, and on the other hand, it can also give full play to JavaScript's flexibility. The advantage of ease of use allows back-end developers to easily develop efficient, stable and scalable web applications.

In summary, JavaScript is a powerful and flexible programming language that can be used for front-end and back-end development to achieve a more interactive and humane user experience. Due to its widespread application and importance, learning JavaScript has become an integral part of the modern IT industry.
