Frequently asked questions
The YouTube video gives you a one-sit overview. The freeCodeCamp.org curriculum (JavaScript Algorithms certification) is interactive, hands-on and ~300 hours — much deeper. Watch the video first, then do the cert.
JavaScript if you want to build websites and see visual results fast. Python if you target data, AI or backend. Both are excellent first languages.
It covers the fundamentals (variables, functions, arrays, DOM). Before React you also need to know arrow functions, destructuring, modules and Promises — covered briefly here, worth a follow-up tutorial.
No — this is free YouTube content. Take freeCodeCamp's separate JavaScript Algorithms and Data Structures certification (also free) for an official badge.
