Sort an array:

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.sort();

// Write `compareStrLength` function

var compareStringLength = function (string1, string2) {

return string1.length - string2.length;

};

// Declare and intitialize `myStringArray`

var myStringArray = ["abc", "a", "abcd", "ab", "gksutbs", "aerus"];

// Sort it

myStringArray.sort(compareStringLength);

// Log it to the console

console.log(myStringArray);
