I know JS basics and I’ve reached the intermediate algorithms of FCC. I’ve a problem that my solutions are not always that efficient. And when I search for better solution, I sometimes don’t understand the solution. Can I go on other algorithms problems or should I stop till I understand their solutions (this takes a lot of time and slows me down).
Continue with other problems - revisit old problems solved and unsolved from time to time as you gain more experience with and insight into problem solving and coding
