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