go is golang. The full name of go is golang, referred to as go language. It is a statically strongly typed, compiled language developed by Google; its main goal is to "have both the development speed of dynamic languages such as Python and the performance and performance of compiled languages such as C/C safety". The launch of the Go language aims to reduce the complexity of the code without losing application performance. It has the advantages of "simple deployment, good concurrency, good language design, and good execution performance".
The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.
There is no difference between go and golang, go is golang, the full name is golang, and the abbreviation is go language.
What is Go language (golang)?
Go (also known as Golang) is a statically strongly typed, compiled language developed by Robert Griesemer, Rob Pike and Ken Thompson of Google. The Go language syntax is similar to C, but its functions include: memory safety, GC (garbage collection), structural form and CSP-style concurrent computing.
Go is a very young language. Its main goal is to "have both the development speed of dynamic languages such as Python and the performance and security of compiled languages such as C/C."
The launch of Go language aims to reduce the complexity of the code without losing application performance. It has the advantages of "simple deployment, good concurrency, good language design, and good execution performance". Currently, many domestic IT companies have adopted Go language to develop projects.
The Go language is sometimes described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.
Because the Go language does not have the concepts of classes and inheritance, it does not look the same as Java or C. But it achieves polymorphism through the concept of interface. The Go language has a clear and easy-to-understand lightweight type system, and there is no hierarchy between types. Therefore, it can be said that Go language is a hybrid language.
Pros:
It has great community support
It got Google Support
It provides fast compile time
It is simple and easy
It is used for Provide high performance.
Disadvantages:
Some libraries are missing in the Go language, especially the UI toolkit.
For Go, all library files must have a single package.
It does not support generics
When working on multiple projects, it creates dependency factors on other artifacts
Characteristics of Go language
Go language ensures that it can achieve the security and performance of statically compiled languages, as well as the performance of dynamic languages. In terms of development speed and ease of maintenance, some people describe Go language: Go = C Python, which means that Go language has the running speed of C static language program and can achieve the rapid development of Python dynamic language.

Go language has the following features:
1. Automatic garbage collection
C /C The most troublesome thing is the pointer problem. If you are not careful, the pointer will be wild or cross the boundary again. In the Go language, there is no need to worry or think about delete or free, the system will automatically recycle it.
2. Functions can return multiple values
This is amazing. Most languages can only return one value, but Go language can return multiple values. This feature eliminates the need for developers to rack their brains to design how to return a value, and there is no need to define a structure specifically for passing values.
3. Concurrent programming
The Go language is naturally concurrent. Only the keyword "go" is needed to execute functions concurrently, making concurrent programming easier. This is also the biggest advantage of Go language.
4. No dependency hell
5. Compile once, copy anywhere, extremely convenient to deploy

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),
