🎁 Free PDF: Senior Developer Starter Kit (Checklist + 30-Day Plan) → https://monsterlessons-academy.com/newsletter_subscribers/senior_starter_kit?utm_source=youtube&utm_medium=description_link 🚀 Go from Middle to Senior Frontend in 12 Weeks → https://monsterlessons-academy.com/courses/frontend-developer-middle-to-senior-bootcamp?utm_source=youtube&utm_medium=description_link In this video you will learn the difference between references in Javascript vs primitives in Javascript.
