The MongoDB web shell is a learning tool that emulates the MongoDB terminal shell for try.mongodb.org, 10gen Education online classes, and the MongoDB API documentation.
This online solution makes it more convenient for users to take courses wherever they may be and makes it easier to validate the correct completion of an assignment. Furthermore, users will no longer be required to load their own datasets using mongorestore since it is handled directly by the shell. Finally, since all the work is stored on their online account, students will be able to continue their work from where they left off from any computer.
