Javascript for password generator 

const PwEl = document.getElementById("pw");
const copyEl = document.getElementById("copy");
const lenEl = document.getElementById("len");
const upperEl = document.getElementById("upper");
const lowerEl = document.getElementById("lower");
const symbolEl = document.getElementById("symbol");
const generateEl = document.getElementById("generate");
const numberEl = document.getElementById("number");
const upperLetters = "ABCDEFGHIJKLMNOPQSRTUVWXYZ";
const lowerLetters = "abcdefghijklmnopqrstuvwxyz";
const numbers = "0123456789";
const symbol = "~!@#$%^&*()_+=|";
function getLowercase() {
return lowerLetters[Math.floor(Math.random() * lowerLetters.length)];
}
function getUppercase() {
return upperLetters[Math.floor(Math.random() * upperLetters.length)];
}
function getNumber() {
return numbers[Math.floor(Math.random() * numbers.length)];
}
function getSymbol() {
return symbol[Math.floor(Math.random() * symbol.length)];
}
function generatePassword() {
const len = lenEl.value;
let password = "";
for (let i = 0; i < len; i++) {
const x = generateX();
password += x;
}
PwEl.innerText = password;
}
function generateX() {
const xs = [];
if (upperEl.checked) {
xs.push(getUppercase());
}
if (lowerEl.checked) {
xs.push(getLowercase());
}
if (numberEl.checked) {
xs.push(getNumber());
}
if (symbolEl.checked) {
xs.push(getSymbol());
}
if (xs.length === 0) return "";
return xs[Math.floor(Math.random() * xs.length)];
}
generateEl.addEventListener("click", generatePassword);
copyEl.addEventListener("click", () => {
const textarea = document.createElement("textarea");
const password = PwEl.innerText;
if (!password) {
return;
}
textarea.value = password;
document.body.appendChild(textarea);
textarea.select();
document.execCommand("copy");
textarea.remove();
alert("password copied to clipboard");
});
