Solution: Word Pattern

Explore how to validate whether a given string follows a specified pattern by creating a one-to-one mapping between pattern characters and words. Learn to implement this using hash maps in JavaScript, ensuring consistent character-to-word mappings, while understanding the time and space complexities involved in the solution.
