The WeChat applet development language is a JavaScript-based development language, specifically using the framework WXML, WXSS and JavaScript encapsulated by WeChat itself.
WXML is a markup language similar to HTML, which can describe the structure of applets. The difference is that WXML tags are simpler and easier to understand. For example, view tags are used instead of div tags in HTML, text tags are used instead of p tags, etc. . WXML also supports data binding, which can bind data to page elements to realize dynamic display of data.
WXSS is a style language similar to CSS, which can describe the style of the applet page. The difference is that the syntax of WXSS is more concise. For example, the rpx unit can be used to adapt to mobile phone screens with different resolutions. At the same time, WXSS also supports common CSS functions such as style inheritance and import, making style writing more convenient.
JavaScript is one of the cores of applet development, which can realize the logic functions of applets. The JavaScript code in the applet is mainly responsible for functions such as data processing, event processing, and interaction with the background interface. JavaScript in applets also supports ES6 syntax, such as arrow functions, let and const keywords, template strings, etc., making development more convenient and efficient.
In general, the WeChat applet development language is a JavaScript-based development language, which has an easy-to-understand WXML markup language, a convenient and efficient WXSS style language, and powerful and flexible JavaScript programming capabilities. These features enable developers to quickly develop small programs and interact with the background interface to achieve richer functions and user experience.
