Calculator Functions Import 
                            It is possible to use the Calculator functions in the JavaScript code. For this purpose, it is required to use the built-in module - "builtIn/Calc". All functions are available, including the ones implemented in plugins, with the exception of the following ones:
- IF, IFF: there is an analogue in JS: 
if (<condition>) {...}. - The functions of work with the input data (
Data,RowNum,RowCount,DisplayName,CumulativeSum): there are analogues in API (RowCount,DisplayName), or they are easily implemented by the JS code. 
Examples of the functions use:
import { OutputTable } from "builtIn/Data";
// Module import by require function
const calcModule = require("builtIn/Calc");
OutputTable.Append();
let currentDate = new Date();
OutputTable.Set(0, calcModule.AddWeek(currentDate, 1));
OutputTable.Set(1, calcModule.AddQuarter(currentDate, -1));
// Import using the default value
import calcDefault from "builtIn/Calc";
OutputTable.Append();
OutputTable.Set(0, calcDefault.Val("1"));
OutputTable.Set(1, calcDefault.Str(1e6));
// Import of the whole module content
import * as calc from "builtIn/Calc";
OutputTable.Append();
OutputTable.Set(0, calc.Count("AAA"));
OutputTable.Set(1, calc.Lower("AAA"));
// Import of certain functions
import { RegExMatchCount, RegExMatchedExp } from "builtIn/Calc";
OutputTable.Append();
OutputTable.Set(0, RegExMatchCount("a+?", "aaa"));
OutputTable.Set(1, RegExMatchedExp("a+", "aaa"));
// Dynamic import
import("builtIn/Calc").then(calc => {
    OutputTable.Append();
    OutputTable.Set(0, calc.Repeat(1, 10));
});
