display-width
A node.js port of uwcwidth, a fast function for determining a string's display width
That code is a port of POSIX wcswidth, a standard function for counting the number of columns occupied by a string, and is derived from musl libc
How to use it
import { wcswidth } from "display-width";
// wcswidth("π©ββ€οΈβπ¨") == 2
console.log(wcswidth("\u{1F469}\u{200D}\u{2764}\u{FE0F}\u{200D}\u{1F468}"));
Why to use it
>> wcswidth("cafeΜ") == 4
>> "cafeΜ".length == 5
>> wcswidth("β οΈ warning") == 9
>> "β οΈ warning".length == 10
>> wcswidth("π¨βπ¨βπ§βπ§") == 2
>> "π¨βπ¨βπ§βπ§".length == 11
>> wcswidth("π©ββ€οΈβπ¨") == 2
>> "π©ββ€οΈβπ¨".length == 8
Is it fast?
yes! Compared to string-width, it's about 33x faster
