The entire course is divided into Levels, with each level having multiple Lessons. Each lesson has a coding exercise.
Here is what our users say about our application and the courses.
I loved your new website, interactive course, the UI is smooth and awesome.
The course was so simple to understand and well explained. You did a great job. I cannot wait to be well established as programmer through this platform Thank you so much, Obrigado!!!
Console output wasn't working when I first tried the lessons (kept showing the blue dots), but after a few attempts seems to be working now.
Great Platfrom to learn coding instant practice make sense
what a best organized and interactive course,, really love this course
Very nice platform for learning any programming language step by step.
Code editor Run button some times disabled it does not enable even after editing. which is exactly come when the console area show s Try Again message. So we have to refresh the page. Otherwise, it was good.
I can say i've learnt a lot form Studytonight. I'm glad i took the web development courses and i will recommend it to everyone who want to start their coding journey :)
To print it to the console is too slow. When you are doing the exercise and you didn't do it well the Run button it gets stuck and I have to refresh the website every time I have a mistake, so I can re-write my code.
Please complete the Course first and then work on Projects.
