A simple way to see how this program was written.
function getString(){
// Get the user's input
let userString = document.getElementById("userString").value;
// Test the user's input for length
// Reverse the input => seperate function
let revString = reverseString(userString);
// Display the result => seperate function
displayString(revString);
}
function reverseString(userString){
// Start at the last index
let startValue = userString.length - 1;
let endValue = 0;
let revString = "";
// In a decremented for loop,
// the start value must be higher than the end value
for(let i = startValue; i >= endValue; i--){
revString += userString[i];
};
return revString
}
function displayString(revString){
let output = document.getElementById("results");
output.innerHTML = revString;
}
