const {GeneratePassword} = require("js-generate-password");
const password = GeneratePassword();
console.log(password);

In the above case, no parameter is passed as option. Therefore the default values will be taken - which will have alphabets, both upper and lower case, numbers, and will be of length 10 characters.
