Scala & Spark-Master Big Data with Scala and Spark - Using Maps for Word Count

This video tutorial explains how to create a program that counts user-entered words using a map. It covers adding new words with an initial count, updating the count for existing words, and handling multiple entries. The tutorial includes a demonstration of the program's functionality and concludes with a preview of the next steps, where users can check the count of specific words.
