String Comparison - Technical Details
Strings that look identical may differ due to invisible characters (zero-width spaces, different whitespace). Hash comparison provides a definitive equality check. Character-by-character diff reveals hidden differences.
Command-line Alternative
// Hash comparison ensures exact match\nSHA256('hello') = 2cf24dba...\nSHA256('hello ') = different!\n\n// Invisible chars: \\u200B, \\u00A0
