Sample Solution:
HTML Code:
<!DOCTYPE html>
<html>

<title>Write a JavaScript to replace each character of a given string by the next one in the English alphabet</title>
</head>
<body>
</body>
</html>
JavaScript Code:
function alphabet_char_Shift(str) {
var all_chars = str.split("");
for(var i = 0; i < all_chars.length; i++) {
var n = all_chars[i].charCodeAt() - 'a'.charCodeAt();
n = (n + 1) % 26;
all_chars[i] = String.fromCharCode(n + 'a'.charCodeAt());
}
return all_chars.join("");
}
console.log(alphabet_char_Shift("abcdxyz"))
Sample Output:

JavaScript: Tips of the Day
Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)
Example:
const isAnagram = (str1, str2) => { const normalize = str => str .toLowerCase() .replace(/[^a-z0-9]/gi, '') .split('') .sort() .join(''); return normalize(str1) === normalize(str2); }; console.log(isAnagram('iceman', 'cinema')); // true
Output:
true
