date.clone()

The clone method creates and returns an independent duplicate of the current NepaliDate instance. Because several library arithmetic and mutation methods alter instances in place, creating a clone allows you to perform calculations without modifying the original date object.

const duplicate = original.clone();

// Mutating duplicate does not impact original
duplicate.setDate(20);

console.log(duplicate.format("YYYY-MM-DD")); // "2081-01-20"
