Calculate the real byte length of any string.

Why

In node many will use Buffer.byteLength, however including the entire buffer shim in the browser just for getting the byte length of a string is not very conservative.

Installation

npm install byte-length

Example

import { byteLength } from "byte-length";

byteLength("hello"); //-> 5
byteLength("😀"); //-> 4
byteLength("ｆｕｌｌｗｉｄｔｈ　ｃｈａｒａｃｔｅｒｓ"); //-> 60
