TypeError: dest.on is not a function! But why?

Question

JavaScript

Everything seems to be according to the documentation, but it does not work. I don't understand. Help / explain to someone is not difficult.

// Определяем константы Gulp
const { src, dest, parallel, series, watch } = require('gulp');

const browserSync = require('browser-sync').create();
const concat = require('concat');
const uglify = require('gulp-uglify-es').default;

function browsersync() {
    browserSync.init({
        server: { baseDir: 'app/' },
        notify: false,
        online: true
    })
}

function scripts() {
    return src([ // Берём файлы из источников
        'node_modules/jquery/dist/jquery.min.js',
        'app/js/app.js',
    ])
        .pipe(concat('app.min.js'))
        .pipe(uglify())
        .pipe(dest('app/js/'))
        .pipe(browserSync.stream())
}

exports.browsersync = browsersync;
exports.scripts = scripts;

Everything related to the error from the console:

Answer 1

Understood. Somehow I installed the wrong package. Now everything works. The question is closed!

Answer 2

So, according to the documentation:
https://www.browsersync.io/docs/gulp/
Pay attention to how browsersync is declared. Or rather gulp. task
