Problem: Valid Anagram

Understand how to verify if one string is an anagram of another by implementing a character frequency hash map. This lesson guides you through comparing string lengths, counting characters, and validating matches efficiently in JavaScript.

Statement

Given two strings s and t, determine whether t is an anagram of s. Return true if it is, and false otherwise.

An anagram is a word formed by rearranging all the letters of another word, using every letter exactly once.

Note: What if the inputs contain Unicode characters? How would you adapt your solution for that case?

Constraints:

  • 11 \leq s.length, t.length 5×104\leq 5 \times 10^4

  • s and ...
