Do I still need to start from bootstrap 3 or I can straight jump start from bootstrap 4+? And I have another doubt about Font Awesome? I found some other links as well apart from the one introduced in FCC. Are they all same or we have more options? Moreover I feel course material for bootstrap and jquery is so less? where can I find more of interactive materials (apart from w3schools, getbootstrap, codecademy and documentation websites) on the subject.
You can definitely start with bootstrap 4. It’s actually easier to learn than bootstrap 3.
