# How to Sort Alphanumeric Strings with JavaScript?

## A guide on sorting alphanumeric strings with JavaScript.

Sometimes, we want to sort alphanumeric strings with JavaScript.

In this article, we’ll look at how to sort alphanumeric strings with JavaScript.

### String.prototype.localeCompare

We can use the string `localeCompare` method to compare strings so we can sort them.

For instance, we can write:

``````const arr = ["123asd", "19asd", "12345asd", "asd123", "asd12"];
const sorted = arr.sort((a, b) => {
return a.localeCompare(b, undefined, {
numeric: true,
sensitivity: "base",
});
});
console.log(sorted);
``````

We call `localeCompare` to compare `a` and `b` naturally.

We set `numeric` to `true` to compare the numerical part of `a` and `b` .

`sensitivity` is set to `'base'` to compare the case and the alphabet.

Therefore, `sorted` is:

``````["19asd", "123asd", "12345asd", "asd12", "asd123"];
``````

### Use Intl.Collator

Also, we can use the `Intl.Collator` constructor to create a collator instance that has the `compare` method to compare 2 strings.

For instance, we can write:

``````const arr = ["123asd", "19asd", "12345asd", "asd123", "asd12"];
const collator = new Intl.Collator(undefined, {
numeric: true,
sensitivity: "base",
});
const sorted = arr.sort((a, b) => {
return collator.compare(a, b);
});
console.log(sorted);
``````

The options are the same as `localeCompare`.

`compare` takes the 2 strings we want to compare.

Then `sorted` is the same result as before.

### Conclusion

This is how we can sort alphanumeric strings naturally with native JavaScript methods.
