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"]
Flowchart:
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
How to insert an item into an array at a specific index (JavaScript)?
What you want is the splice function on the native array object.
arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:
var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
