I'm working on a discord command that converts text to braille. I've found a few web-based examples of converting to other things such as morse code and tried to modify them but nothing seems to work.

The basic idea is that it would take in a string convert each character in the string to its braille equivalent and send that as an output.

Any help would be wonderful thanks <3

string.toUpperCase().split("").map(c => "⠀⠁⠂⠃⠄⠅⠆⠇⠈⠉⠊⠋⠌⠍⠎⠏⠐⠑⠒⠓⠔⠕⠖⠗⠘⠙⠚⠛⠜⠝⠞⠟⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿"[" A1B'K2L@CIF/MSP\"E3H9O6R^DJG>NTQ,*5<-U8V.%[$+X!&;:4\\0Z7(_?W]#Y)=".indexOf(c)]).join("");

One liners are cool, but here is a slightly better variation of the same code.

let map = " A1B'K2L@CIF/MSP\"E3H9O6R^DJG>NTQ,*5<-U8V.%[$+X!&;:4\\0Z7(_?W]#Y)=".split("").reduce((o, n, i) => {
  return o[n] = "⠀⠁⠂⠃⠄⠅⠆⠇⠈⠉⠊⠋⠌⠍⠎⠏⠐⠑⠒⠓⠔⠕⠖⠗⠘⠙⠚⠛⠜⠝⠞⠟⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿"[i],
    o[n.toLowerCase()] = o[n], o;
}, {});

function toBraile(string) {
    return string.split("").map(c => map[c]).join("");
}

console.log(toBraile("test="));

Perhaps the conversion of split("") and join("") can also be improved, I'd be happy if someone has something to say on that.

Braille strings snatched from the braile ascii wikipedia page.
