With the continuous development of the Internet, JavaScript has become an increasingly popular programming language and is widely used in website development, application and game creation. JavaScript can be said to be one of the essential skills for front-end development, but how powerful is it?
First of all, JavaScript is a dynamic language, that is, the code structure and variable types can be changed freely at runtime. This makes JavaScript very flexible and able to meet a variety of different programming needs. Compared with static languages, JavaScript has higher programming efficiency and flexibility because it does not need to define all variable types in advance.
Secondly, JavaScript also has some powerful frameworks and libraries, such as React, Angular, and Vue. These frameworks and libraries can greatly simplify the development process and provide developers with a range of tools and features to improve application performance and scalability. With these tools, JavaScript developers can easily build user interfaces, process data, build modular applications, and more.
In addition, JavaScript can also be used for server-side programming. Node.js is a server-side runtime environment based on JavaScript, which allows JavaScript to gain equivalent functionality to other back-end languages. This capability allows JavaScript to easily share code and data between front and back ends, improving development efficiency and cross-platform reliability.
Although JavaScript excels in front-end development, web applications, and games, it also has some limitations. First, JavaScript code executes slower than some compiled languages (such as C and Java), which can affect application performance. Secondly, JavaScript is susceptible to hacking and abuse, so it must be used with caution and appropriate security measures in place.
In general, JavaScript can be said to be a powerful programming language. It has many advantages and features that make it easy to build modern web applications and games, and can also be used for server-side programming. However, JavaScript has limitations that we also need to pay attention to and overcome. In the future, as technology continues to develop, we can expect JavaScript to become more and more powerful in all aspects.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
