Java and JavaScript are two completely different programming languages that differ in many ways. Java is an object-oriented programming language originally developed by Sun Microsystems. It is a compiled language, which requires the code to be converted into an executable language before compilation. In contrast, JavaScript, a scripting language originally developed by Netscape, is an interpreted language whose code is interpreted into an executable language at runtime.
While both languages are closely related to web development, there are clear differences in their design and purpose. Java is often used to build highly scalable and secure enterprise-level applications, while JavaScript is used to enable interactivity and dynamics in web browsers. Therefore, in order to understand the difficulty of these two languages, it is necessary to have a certain understanding of their application scenarios and implementation details.
The learning curve of Java is relatively long. A good Java programmer needs to learn many concepts and technologies, including object-oriented programming, concurrent programming, generics, exception handling, JDBC, Servlet, JSP, Spring Framework, etc. In addition, you also need to have relevant knowledge of Java platforms such as Java SE, Java EE or Java ME. This knowledge requires a certain amount of time and energy to master, so Java may be difficult for beginners.
In contrast, JavaScript may be easier to get started with. Its syntax is relatively simple and makes it easy to create dynamic web pages. Additionally, JavaScript integrates well with other web technologies, such as HTML and CSS. However, although JavaScript has a lower entry barrier than Java, it still takes a lot of effort and time to truly master the advanced concepts and technologies of JavaScript. These concepts and techniques include closures, prototypes, scope chains, asynchronous programming, event handling, and more.
All in all, Java and JavaScript are complex programming languages that require a lot of time and effort to master. Whether a person finds one of the languages more difficult may depend on their background and experience. No matter which language you choose, it will take consistent study and practice to achieve success.

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),
