You'll start writing code almost immediately once you start the lessons, completing 1200 programming tasks and getting immediate results for your solutions. Over a million programmers use HackerRank to hone their development skills by solving code challenges.
When you first start learning to code, it can seem like a monumental task that requires months or years to make significant progress. Codecademy offers both free and paid courses, so you can customise your learning to suit your needs and budget. But in reality, Code Avengers is an online platform with a mix of free coding classes and premium courses.
