I think it useful when learning a new language or framework. When you are completely new you can spend 90% of the time just searching for trivial answers. It also takes longer to search because you don't know really how to frame the question. I find it more useful to go quickly go through a book or online course and try to memorize some of the basics from the book before starting. Not reviewing earlier topics results in very little retention.
