toSorted() array method

Today I learned that there is a newish javascript array method toSorted() which is the “copying” or non-mutating version of sort().

This means you can easily sort an array by getting back a new copy instead of mutating the original:

const months = ["Mar", "Jan", "Feb", "Dec"];
const sortedMonths = months.toSorted();
console.log(sortedMonths); // ['Dec', 'Feb', 'Jan', 'Mar']
console.log(months); // ['Mar', 'Jan', 'Feb', 'Dec']

It’s pretty cool to see javascript moving more towards immutability. I mentioned the with() method before and now there is also toReversed() and toSpliced().

These were added in ES2023 and have been available in browsers since July 2023.
