Somebody asked me how to do an encryption just like if we type “a” it should return “d” (3 letters after “a” position).
I can give a kind of clue, but it needs improvements though.
Check out this source code:

<body>
<h1>Another Simple JavaScript Encryption</h1>
<input id="originaltext"><br>
<button onclick="encrypt()">Encrypt</button>
<p id="er">Encryption Result</p>
<script>
var letters = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"];
function encrypt(){
var originalText = document.getElementById("originaltext").value;
var tempVar = "";
for(var i = 0; i < originalText.length; i++){
for(var z = 0; z < letters.length; z++){
if(originalText[i] == letters[z]){
tempVar += letters[z+3];
}
}
}
document.getElementById("er").innerHTML = tempVar;
}
</script>
</body>
</html>
See how it works in this video:
