Ordering string in an array according to a number in the string JavaScript

JavascriptWeb DevelopmentObject Oriented Programming

We have an array of strings each of which contain one or more numbers like this −

const arr = ['di5aster', 'ca1amity', 'cod3', 'ho2me3', 'ca11ing'];

We are required to write a sorting function that sorts this array in ascending order of the numbers present in the strings. The correct order will be −

const output = [ 'ca1amity', 'cod3', 'di5aster', 'ca11ing', 'ho2me3' ];

Therefore, let’s write the code for this problem −

Example

const arr = ['di5aster', 'ca1amity', 'cod3', 'ho2me3', 'ca11ing'];
const filterNumber = str => {
   return +str
   .split("")
   .filter(el => el.charCodeAt() >= 48 && el.charCodeAt() <= 57)
   .join("");
};
const sorter = (a, b) => {
   return filterNumber(a) - filterNumber(b);
};
arr.sort(sorter);
console.log(arr);

Output

The output in the console will be −

[ 'ca1amity', 'cod3', 'di5aster', 'ca11ing', 'ho2me3' ]
