To further prove my point, MongoDB is ranked fifth overall on the website DB-Engines (https://db-engines.com/en/ranking) and ranked first under the category of Document Stores (https://db-engines.com/en/ranking/document+store).
It is clear that MongoDB is here to stay, and more importantly, that the community loves MongoDB. This is very important, because it creates a healthy community of developers that share knowledge and articles on MongoDB. Broad adoption of MongoDB furthers the development of the technology.
