These are some great online resources used by me to learn to write code.
- DevProjects is really special. I really like this one because they give you real world scenario projects that you create solutions for. You can even put your solution on your resume. The URL is: https://www.codementor.io
- Sololearn is truly free, but also very high quality. https://www.sololearn.com
- Programiz Interactive and very good. I have only played around with this one so far however. I will report back with more information as I put more hours into it. However it does seem very good. https://www.programiz.com/
That is all for now! Although there are many many more sites these are the ones I have used and can recommend confidently and with a good conscience. Enjoy!
