Usage Examples

import { hashString } from "@zsqk/somefn/js/hash";
import { fieldCalculate } from "@zsqk/somefn/js/calculate-field";
import { logicCalculate, LogicOperator } from "@zsqk/somefn/js/calculate-logic";
import { getWeekday } from "@zsqk/somefn/js/date";

// Hash calculation example
const hash = await hashString("hello world", "SHA-256");
console.log(hash); // Outputs SHA-256 hash value

// Field calculation example
const data = { price: 100, quantity: 2 };
const total = fieldCalculate(data, "price * quantity".split(" "));
console.log(total); // Output: 200

// Logic calculation example
const logicData = { age: 25, name: "John" };
const result = logicCalculate(logicData, {
  condition: "AND",
  rules: [
    { field: "age", operator: LogicOperator.greaterThan, value: 18 },
    { field: "name", operator: LogicOperator.equals, value: "John" }
  ]
});
console.log(result); // Output: true

// Date calculation example
const before = new Date("2024-01-01");
const after = new Date("2024-01-31");
const weekdays = getWeekday(before, after);
console.log(weekdays); // Outputs weekday statistics
