функция текстовых подсказок работает неправильно (совсем не работают), города парсятся из russia.json с лишними символами const cities = [&#34 ;Москва",“Абрамцево” https://www.codetable.net/decimal/34

Нужно заменить jquery более простым решением, другим пакетом или pure javascript, чтобы появлялись текстовые варианты из городов и автозаполнялись. вот код:

app.js:
const express = require(“express”);
const fs = require(“fs”);
const session = require(“express-session”);
const fileUpload = require(“express-fileupload”);
const app = express();
const fuzzball = require(“fuzzball”);

app.set(“view engine”, “ejs”);
app.use(express.static(“public”));

app.use(express.urlencoded({ extended: true }));
app.use(fileUpload());
app.use(session({
secret: “mysecretkey”,
resave: false,
saveUninitialized: false
}));






const citiesAndRegions = JSON.parse(fs.readFileSync(“./db/russia.json”, “utf8”));


const predefinedGenres = [‘Rock’, ‘Pop’, ‘Jazz’, ‘Hip Hop’, ‘Electronic’, ‘Blues’];

function getMusicianById(id) {
const data = fs.readFileSync(“./db/musicians.json”);
const musicians = JSON.parse(data);

return musicians.musicians.find(musician => musician.id === id);
}

function requireLogin(req, res, next) {
if (req.session.musicianId) {
next();
} else {
res.redirect(“/login”);
}
}

function search(query = ‘’, role = ‘’, city = ‘’) {
const data = fs.readFileSync(‘./db/musicians.json’);

const musicians = JSON.parse(data).musicians.map(musician => {
return {

genre: musician.genre,
originalName: musician.name,

};
});

let results = [];

if (query || role || city) {
const lowerQuery = query.toLowerCase();
results = musicians.filter(musician => {
const nameScore = musician.name.toLowerCase().startsWith(lowerQuery) ? 2 : musician.name.toLowerCase().includes(lowerQuery) ? 1 : 0;
const genreScore = musician.genre.toLowerCase().startsWith(lowerQuery) ? 2 : musician.genre.toLowerCase().includes(lowerQuery) ? 1 : 0;

return (
nameScore + genreScore > 0 &&

return 1;

}

// Remove duplicates
