Is it necessary to redo the exercise if I have already completed it?
I went back to see the completed exercises and they are correct, but the exercise is as if I have not done it.
Thank you for your answers.
Only the projects are required. The other challenges are there to help you learn. You don’t have to repeat things that you already know.
I wanted to see what code I had written in those completed exercises.
Thanks for the answer.
If you think you don’t understand a certain exercise yet, completely, don’t hesitate to come back to it.
I believe the code you wrote is just cached in your browser. So if its not there it is gone.
I realized that u can save only one excersise in ur browser, and that’s all.
I think I’ll review, writing everything again
But when I want to come back the exercise is in blank, like if you were to make it from the beginning.
Yeah, I don’t believe the exercises save your code. They are just short quizzes to help you learn, but don’t perform any type of save, so once you’ve moved on to the next exercise, your previous answers are gone. I found it helpful to take notes as I progressed, because there were definitely instances when working on the projects that I wanted to go back and look at my challenge code to remind myself of the syntax, but it wasn’t there.
There are two different types of saved progress for Free Code Camp: your profile and your browser cache.
A list of your completed challenges is saved to your account in the FCC database. You can see the list of completed challenges by looking at your public portfolio. With a growing curriculum already over 1,400 lessons and a community of millions of people, FCC does not store every solution to every challenge in its database. When you complete a challenge, there is a modal that gives you the option to download your solution. This gives you the option to save a copy of any solution that you may want to reference later. There are some challenges which are classified as projects required for certifications. Your solutions to those can be viewed on your settings page.
Your in-editor code is saved in your browser’s local storage. Recent in-progress code from the challenge editor is also saved in your local browser cache when you run tests. If you are completing lessons and do not see your recent code, then your local storage has been cleared or something is preventing FCC from writing to your browser’s storage. This could be a browser setting, a privacy extension, or a browser version incompatibility. Especially as you get to more complicated challenges that may take multiple sessions, I strongly recommend saving your in-progress work outside of the browser cache.
This is a good opportunity to learn the ins and outs of your GitHub account, but you can also just save locally or use a service like repl.it which allows for versioning.
