MongoDB Mastering MongoDB for Beginners (Theory and Projects) - $mod Operator

The video tutorial introduces the mod operator, explaining its basic functionality and practical applications. It demonstrates how to use the mod operator to query documents based on even and odd quantities. The tutorial also covers writing queries using the mod operator and concludes with a preview of upcoming quizzes to reinforce learning.

What is the primary function of the mod operator as discussed in the video?

• To find the remainder of a division

• To subtract one number from another
