JavaScript: Sort the strings of a given array of strings in the order of increasing lengths

JavaScript Basic: Exercise-143 with Solution

Write a JavaScript program to sort the strings of a given array of strings in the order of increasing lengths.

Note: Do not change the order if the lengths of two string are same.

Pictorial Presentation:

JavaScript: Sort the strings of a given array of strings in the order of increasing lengths.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Sort the strings of a given array of strings in the order of increasing lengths.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function sort_by_string_length(arra) {
	for (var i = 0; i < arra.length; i++) {
		for (var j = i + 1; j < arra.length; j++) {
			if (arra[i].length > arra[j].length) {
				var m = arra[i];
				arra[i] = arra[j];
				arra[j] = m;
			}
		}
	}
	return arra;
}
var arra = ["xyz","acd","aa","bb","zzz","", "a","b"];
console.log("Original array: "+ arra+"\n");
console.log(sort_by_string_length(["xyz","acd","aa","bb","zzz","", "a","b"]));

Sample Output:

Original array: xyz,acd,aa,bb,zzz,,a,b

["","a","b","bb","aa","xyz","acd","zzz"]

ES6 Version:

function sort_by_string_length(arra) {
	for (let i = 0; i < arra.length; i++) {
		for (let j = i + 1; j < arra.length; j++) {
			if (arra[i].length > arra[j].length) {
				const m = arra[i];
				arra[i] = arra[j];
				arra[j] = m;
			}
		}
	}
	return arra;
}
var arra = ["xyz","acd","aa","bb","zzz","", "a","b"];
console.log("Original array: ",arra);
console.log(sort_by_string_length(["xyz","acd","aa","bb","zzz","", "a","b"]));

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
