Difference: 1. TS is a free open source programming language developed and maintained by Microsoft; while ES6 is an ECMA internationally standardized scripting language specification. 2. TS supports all primitive data types, but ES6 does not. 3. TS has 3 scopes and ES6 has 2. 4. TS modules are divided into internal and external modules, and ES6 modules are divided into import and export modules.
The operating environment of this tutorial: Windows 7 system, ECMAScript version 6, Dell G3 computer.
I believe everyone has some understanding of ts (TypeScript) and es6. What are the differences between them? Here are a few summary points.
What is TypeScript (TS for short)?
TypeScript is a free and open source programming language developed by Microsoft. It is a superset of JavaScript and essentially adds optional static typing and class-based object-oriented programming to the language.
TypeScript extends the syntax of JavaScript, so any existing JavaScript program can work under TypeScript unchanged. TypeScript is designed for large-scale application development, and it generates JavaScript when compiled to ensure compatibility.
TypeScript supports header files that add type information to existing JavaScript libraries, extending its benefits to popular libraries such as jQuery, MongoDB, Node.js, and D3.js.
What is ES6?
ECMAScript is a scripting programming language standardized by Ecma International (formerly the European Computer Manufacturers Association) through ECMA-262.
And ES6 is ECMAScript 6, which is the next generation standard of JavaScript language and was officially released in June 2015. Mozilla will launch JavaScript 2.0 based on this standard.
The goal of ES6 is to enable the JavaScript language to be used to write large and complex applications and become an enterprise-level development language.
The difference between TypeScript and ES6
1. TypeScript is a free open source programming language developed and maintained by Microsoft. ES6 is a version of ECMAScript (ES), which is ECMA's internationally standardized scripting language specification.
2. TypeScript supports all primitive data types, but ES6 does not.
3. Variable scope
TypeScript has three scopes: global scope, class scope, and local scope.
ES6 has two scopes: global scope and local scope.
4. Module
In TypeScript, there are two types of modules: internal and external modules. In ES6, modules are divided into import modules and export modules.
5. ES6 mainly tends to be built in needed tools or small projects. If we need a robust testing workflow, we need to remember one thing, then we have to use ES6.

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),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
