Isomorphic Strings using JavaScript Map
by landro
Below is a logic puzzle called Isomorphic Strings I have no idea where this came from, but have run into it a couple times playing with leetcode or other frontend learning resources. What got me excited was the opportunity to use JavaScript's Map() feature to hold the Key-Value pairs in the comparison. I feel that it makes the isomorphic string matching implementation much more readable & maintainable.
The Isomorphic Strings Problem
Two strings string1 and string2 are called isomorphic if there is a one to one mapping possible for every character of string1 to every character of string2. And all occurrences of every character in string1 map to same character in string2
See the Pen Isomorphic Strings with Map() by jlandro (@adhocracy) on CodePen.
