Do WeChat mini programs use JavaScript?

With the development of mobile Internet, WeChat mini programs have become an indispensable part of people's lives. WeChat mini programs have the characteristics of small size, fast downloading, multiple functions, and simple operation. They have become one of the main channels for corporate publicity, brand promotion and product sales. However, I believe many people will wonder, does WeChat applet use JavaScript?

WeChat applet is a lightweight application based on the WeChat platform and runs in the WeChat environment. WeChat mini programs are different from ordinary mobile applications. Mini programs only need to be downloaded once and can be accessed directly in WeChat without installation or upgrade, which is very convenient. In the mini program, we can write code in JavaScript language to implement various functions.

JavaScript is a lightweight programming language invented by Netscape and released in 1995. It is an object- and event-driven scripting language. JavaScript language can realize the dynamic effects of web browsers, form validation, user input detection and other functions, and is widely used in web development, desktop application development and server-side application development and other fields.

Compared with ordinary web pages, the JavaScript of WeChat mini programs needs to implement more functions and interactive effects. In the mini program, the API provided by WeChat can be called through JavaScript language to implement functions such as sharing in WeChat Moments, WeChat payment, and WeChat login. At the same time, third-party frameworks and libraries can also be used in mini programs, such as the WePY framework and UniApp framework developed by Tencent, to assist in code writing and development.

When using JavaScript to write code in a small program, you need to follow certain specifications and styles. For example, the code needs to be organized according to a fixed file structure, the code needs to be written using ES6 syntax specifications, the specifications in the WeChat applet development documentation need to be followed, etc. Complying with these specifications and styles helps to improve the readability and maintainability of the code and reduce code redundancy and errors.

To sum up, WeChat applet can be coded using JavaScript language. As a lightweight programming language, JavaScript has the advantages of rapid development, cross-platform operation, and simplicity and ease of learning. It is suitable for coding WeChat mini programs. However, during the code writing process, you need to pay attention to following the specifications and style of the WeChat applet to ensure the effectiveness and efficiency of the code.
