Valid Anagram

Understand how to verify if one string is an anagram of another by effectively tracking character counts. Learn the key constraints and apply coding techniques to implement solutions in JavaScript, strengthening your problem-solving skills for coding interviews.

Statement

Given two strings, str1 and str2, check whether str2 is an anagram of str1.

An anagram is a word or phrase created by rearranging the letters of another word or phrase while utilizing each of the original letters exactly once.

Constraints:

  • 11 \leq str1.length, str2.length 103\leq 10^3

  • str1 and str2 consist of only lowercase English letters.
