SwapCase - ToyProblem

1.3.js

// Swap Case
// Below is a function that takes in a string and reverses the case of every character and returns the new string.
// It is currently in a broken state and does not run properly.
// It is possible to fix the code by only modifying the existing code, not adding new lines.

//test data
//'This Is An Example' becomes 'tHIS iS aN eXAMPLE'
//'boB rOss IS thE OrIgInAl GanGster' Becomes 'BOb RoSS is THe oRiGiNaL gANgSTER'
