Random Password Generator

This project practices functions, strings, conditionals, loops, arrays, and random selection.

Concepts Practiced

Code

function generatePassword(
  length,
  includeLowercase,
  includeUppercase,
  includeNumbers,
  includeSymbols,
) {
  const lowercaseChars = "abcdefghijklmnopqrstuvwxyz"
  const uppercaseChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
  const numberChars = "0123456789"
  const symbolChars = "!@#$%^&*()_+="
 
  let allowedChars = ""
  let password = ""
 
  allowedChars += includeLowercase ? lowercaseChars : ""
  allowedChars += includeUppercase ? uppercaseChars : ""
  allowedChars += includeNumbers ? numberChars : ""
  allowedChars += includeSymbols ? symbolChars : ""
 
  if (length <= 0) {
    return "Password length must be at least 1"
  }
 
  if (allowedChars.length === 0) {
    return "At least one character type must be selected"
  }
 
  for (let i = 0; i < length; i++) {
    const randomIndex = Math.floor(Math.random() * allowedChars.length)
    password += allowedChars[randomIndex]
  }
 
  return password
}
 
const passwordLength = 12
const includeLowercase = true
const includeUppercase = true
const includeNumbers = true
const includeSymbols = true
 
const password = generatePassword(
  passwordLength,
  includeLowercase,
  includeUppercase,
  includeNumbers,
  includeSymbols,
)
 
console.log(`Generated password: ${password}`)
