Why Sololearn does not want to update some courses?

Question

The PHP course seems incomplete to me, because there is no OOP, examples of error handling, connection to database. In Java course there is no explanation of JVM, in CSS- preprocessors and Bootstrap, in JS- some popular frameworks(e.g. Angular, React),etc. Is Sololearn going to uptade the lessons?

Answer 1

If you want to learn advanced php...go to Udacity. It has free video and quiz based courses.
