This article mainly introduces you to the relevant information on how to use javascript to randomly generate a certain number of passwords. The article gives detailed js sample code, which is of certain significance to your study or work. Reference learning value, friends who are interested in JavaScript, please follow the editor to learn together.
Preface
This article mainly introduces the relevant content about using javascript to randomly generate a certain number of passwords, and shares it for your reference and study. , not much to say below, let’s take a look at the detailed introduction.
Requirements
Randomly generate a certain number of passwords. There is a minimum number and a maximum number. It must contain numbers, uppercase and lowercase letters, and special characters such as (- _ #);
code
function createPassword(min,max) {
//可以生成随机密码的相关数组
var num = ["0","1","2","3","4","5","6","7","8","9"];
var english = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"];
var ENGLISH = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"];
var special = ["-","_","#"];
var config = num.concat(english).concat(ENGLISH).concat(special);
//先放入一个必须存在的
var arr = [];
arr.push(getOne(num));
arr.push(getOne(english));
arr.push(getOne(ENGLISH));
arr.push(getOne(special));
//获取需要生成的长度
var len = min + Math.floor(Math.random()*(max-min+1));
for(var i=4; i<len; i++){
//从数组里面抽出一个
arr.push(config[Math.floor(Math.random()*config.length)]);
}
//乱序
var newArr = [];
for(var j=0; j<len; j++){
newArr.push(arr.splice(Math.random()*arr.length,1)[0]);
}
//随机从数组中抽出一个数值
function getOne(arr) {
return arr[Math.floor(Math.random()*arr.length)];
}
return newArr.join("");
}use
Pass in the minimum number of digits and the maximum number of digits in a generated password to return a random password
console.log(createPassword(8,15));
The above is all the content of this article, I hope Provide help for everyone's learning.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AMThe shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AMJavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

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.
