@compute.ts/function

Presentation

The engine is based on incremental computation algorithms. When a calculation is submitted to the engine, all the computed values are memorized. So, if you change some variable and query an evaluation, the engine is able to compute the result very fast because it recomputes only what has changed.

Libraries

The project provides several libraries that each comes with dozens of operators. Please note the cross-compatibility of the libraries.

• @compute.ts/boolean
• @compute.ts/number
• @compute.ts/string
• @compute.ts/date
• @compute.ts/dictionary
• @compute.ts/array
• @compute.ts/math
• @compute.ts/structural

Imports

Typescript

import {/* required operators */} from '@compute.ts/function';

Javascript

const {/* required operators */} = require('@compute.ts/function');

Operators

Function

Function.takeType.returnType.code(value) ➜ xfunction

The Function operator allows you to create an expression which evals to the result of the given fuction. If no value is provided the expression is a variable of the model

import {Function} from "@compute.ts/function";

const x = Function
    .takeNumberArray
    .takeNumber
    .returnNumberArray
    .code((array: number[], threshold: number) => {
        return array.filter(value => value < threshold);
    });

---

apply

xfunction.apply(x0type-A, x1type-B, x2type-C) ➜ xtype-return

The apply operator allows to create a boolean expression which evals to the result of the function according to the value of the agument(s)

import {Function} from "@compute.ts/function";
import {array} from "@compute.ts/array";
import {number} from "@compute.ts/number";

const x = Function
    .takeNumberArray
    .takeNumber
    .returnNumberArray
    .code((y1: number[], y2: number) => {
        return y1.filter(v => v < y2);
    });

const y1 = array.ofNumber([1, 2, 3, 4]);
const y2 = number();
const z = x.apply(y1, y2);

y2.affect(3)
const value = z.eval(); // [1, 2]
