JavaScript language (JavaScript Programming Language)

 

JavaScript (JS for short) is currently a scripting language widely used in web browsers. JavaScript is an interpreted language and does not need to be compiled in advance, and is directly executed on the browser.

The JavaScript language can also be applied (implemented) elsewhere, but it is most commonly used in web client browsers.

JavaScript was originally developed and designed by Brendan Eich of Netscape. JavaScript is a dynamically typed, weakly typed, prototype based object oriented programming language. In addition, JavaScript is a standard developed by ECMA International , named ECMAScript (standard number ECMA-262 ).

Why learn JavaScript?

JavaScript is one of the three basic languages ​​for web development:

• HTML : Describe the content and structure of a web page
• CSS: Describe how the web interface is presented
• JavaScript: Describe the behavior of the webpage, allowing the webpage to interact with users and servers

For web front-end developers, JavaScript is a must-learn skill!

Is there a relationship between JavaScript and Java?

People who are new to JavaScript often have questions. The answer is no, don't be confused.

In 1995, JavaScript was first launched with Netscape 2.0. It was originally named LiveScript, but because of the marketing strategy to emphasize the universality of Sun Sun’s Java programming language, it was renamed JavaScript, even if there was not much difference between Java and JavaScript. Since then, this has become the culprit of confusion.
