Typescript - Sort strings descending

Question

I'm trying to sort a string[] in descending way. So far what I have done is the code below:

let values = ["Saab", "Volvo", "BMW"]; // example   values.sort(); values.reverse(); 

It's working but I'm trying to figure out if there is a better way to do it.

Answer 1

You need to create a comparison function and pass it as a parameter of sort function:

values.sort((one, two) => (one > two ? -1 : 1)); 

Answer 2

A more current answer is that you can utilize String.prototype.localCompare() to get a numeric comparison value

Simple example:

let values = ["Saab", "Volvo", "BMW"]; values.sort((a, b) => b.localeCompare(a)) 

This also wont causes TypeScript warnings as the output of localCompare is a number
