pure JS

Based on pure JS functionality but you can extend and combine any libraries you want
Modify the nemathode.pure.config.js file:
nemathode.pure.config.js
module.exports = {
    mathConstants: {
        'E': Math.E,
        'LN2': Math.LN2,
        'LN10': Math.LN10,
        'LOG10E': Math.LOG10E,
        'LOG2E': Math.LOG2E,
        'PI': Math.PI,
        'SQRT1_2': Math.SQRT1_2,
        'SQRT2': Math.SQRT2,
    },
    functions: {
        'abs': {
            implementation: Math.abs,
        },
        'min': {
            implementation: Math.min,
        },
        'areEqual': {
            implementation: (...args: number[]): boolean => {
                return args.every(v => v === args[0]);
            },
        },
    },
    toInputType: (val: unknown): unknown => val,
    toOutputValue: (val: unknown): unknown => val,
    binaryOperators: {
        '+': {
            precedence: 1,
            implementation: (l: number, r: number): number => {
                return l + r;
            },
        },
        '-': {
            precedence: 1,
            implementation: (l: number, r: number): number => {
                return l - r;
            },
        },
        '*': {
            precedence: 2,
            implementation: (l: number, r: number): number => {

        '/': {

            },
        },
        '%': {

            implementation: (l: number, r: number): number => {
                return l % r;
            },
        },
    },
};
