Sort mixed alpha/numeric array

var reA = /[^a-zA-Z]/g;
var reN = /[^0-9]/g;

function sortAlphaNum(a, b) {
  var aA = a.replace(reA, "");
  var bA = b.replace(reA, "");
  if (aA === bA) {
    var aN = parseInt(a.replace(reN, ""), 10);
    var bN = parseInt(b.replace(reN, ""), 10);
    return aN === bN ? 0 : aN > bN ? 1 : -1;
  } else {
    return aA > bA ? 1 : -1;
  }
}
console.log(
["A1", "A10", "A11", "A12", "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"].sort(sortAlphaNum)
)

const sortAlphaNum = (a, b) => a.localeCompare(b, 'en', { numeric: true })

Usage:

const sortAlphaNum = (a, b) => a.localeCompare(b, 'en', { numeric: true })
console.log(['A1', 'A10', 'A11', 'A12', 'A2', 'A3', 'A4', 'B10', 'B2', 'F1', 'F12', 'F3'].sort(sortAlphaNum))

Gives:

["A1", "A2", "A3", "A4", "A10", "A11", "A12", "B2", "B10", "F1", "F3", "F12"]

You may have to change the 'en' argument to your locale or determine programatically but this works for english strings.

localeCompare is supported by IE11, Chrome, Firefox, Edge and Safari 10.

I had a similar situation, but, had a mix of alphanumeric & numeric and needed to sort all numeric first followed by alphanumeric, so:

A10
1
5
A9
2
B3
A2

needed to become:

1
2
5
A2
A9
A10
B3

I was able to use the supplied algorithm and hack a bit more onto it to accomplish this:

var reA = /[^a-zA-Z]/g;
var reN = /[^0-9]/g;
function sortAlphaNum(a,b) {
    var AInt = parseInt(a, 10);
    var BInt = parseInt(b, 10);

    if(isNaN(AInt) && isNaN(BInt)){
        var aA = a.replace(reA, "");
        var bA = b.replace(reA, "");
        if(aA === bA) {
            var aN = parseInt(a.replace(reN, ""), 10);
            var bN = parseInt(b.replace(reN, ""), 10);
            return aN === bN ? 0 : aN > bN ? 1 : -1;
        } else {
            return aA > bA ? 1 : -1;
        }
    }else if(isNaN(AInt)){//A is not an Int
        return 1;//to make alphanumeric sort first return -1 here
    }else if(isNaN(BInt)){//B is not an Int
        return -1;//to make alphanumeric sort first return 1 here
    }else{
        return AInt > BInt ? 1 : -1;
    }
}
var newlist = ["A1", 1, "A10", "A11", "A12", 5, 3, 10, 2, "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"].sort(sortAlphaNum);

A simple way to do this is use the localeCompare() method of JavaScript https://www.w3schools.com/jsref/jsref_localecompare.asp

Example:

export const sortAlphaNumeric = (a, b) => {
    // convert to strings and force lowercase
    a = typeof a === 'string' ? a.toLowerCase() : a.toString();
    b = typeof b === 'string' ? b.toLowerCase() : b.toString();

    return a.localeCompare(b);
};

Expected behavior:

10X Radonius
200X Radonius
20X Radonius
20X Radonius Prime
30X Radonius
40X Radonius

You can use Intl.Collator

It has performance benefits over localeCompare Read here

Browser comparability ( All the browser supports it )

let arr = ["A1", "A10", "A11", "A12", "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"]

let op = arr.sort(new Intl.Collator('en',{numeric:true, sensitivity:'accent'}).compare)

console.log(op)
