Summary

In this chapter, we discussed many topics surrounding concurrency in web scraping. We looked at what concurrency is and how we can benefit from it. We reviewed some of the common issues that must be avoided when building concurrent programs. We also learned about the Go concurrency model and how to use its primitive objects to build concurrent Go applications. Finally, we looked at a few of the niceties Go has included in its sync package. In our final chapter, we will look at taking our scraper to the highest level.
