A simple tool to change lowercase letter to uppercase letter randomly in string.
Tips: This package was actually on npmjs.org for a few years, but due to a mistake by npmjs, it was deleted and could not be restored. npmjs suggested that I should re-upload it.
First, install it from NPM
npm install randomuppercase
Second, import & code
const ruc = require("randomuppercase");
console.log(ruc("abcd1234"));
The length of the string should be long than 5. license MIT
