The aim of this puzzle: Print out each letter, but change the T’s to U’s

Walkthrough of the solution: The for...of loop will store each letter of 'GATTACA' in element. Before the element is printed, we need to check if the letter is a 'T'. If it is, then we should switch the letter to a 'U' first. Inside the curly brackets of the If Statement, add element = 'U'.

Sample code solution:
(Tap below to reveal)

var sequence = 'GATTACA';
for (var element of sequence) {
  if (element === 'T') {
    element = 'U';
  }
  print(element);
}
