Background
The Taco Cat coding challenge is based on the more traditional “Reverse a string” exercise but ultimately determines if a word or phrase is a palindrome. The Reverse a string exercise in some form has been used by technology companies such as Amazon, Microsoft, VMware and Norton to assess a candidate’s ability to code an impromptu algorithm.
Description
Write a program that allows a user to enter in a word or phrase and then prints out the reverse of what was entered. Example: the user enters “developer” the output is “repoleved”.
Determine if the word or phrase entered by the user is a palindrome. Example: “Tacocat”.
Solve
Wild Encounter! Tacocat!
Code
The following is my JavaScript code used for this exercise. Read over if your interested.
document.getElementById("flipBtn").addEventListener("click", tacocat);
function tacocat() {
//Button clicked event
//Step 1
//Retreiving Data
let userInput = document.getElementById("reverseString").value;
//Step 2
//Work with the gathered data
let palinWord = ""
for (let loop = userInput.length - 1; loop >= 0; loop--) {
palinWord += userInput.charAt(loop).toLowerCase();
};
//Step 3
//Result
if (userInput == palinWord) {
swal("Gotcha!", "Tacocat was caught!", "success");
} else {
swal("Sorry!", "Tacocat fainted! you gained 500 XP!", "error");
}
document.getElementById("reverseOutput").innerHTML = palinWord;
