Logical gates defined as simple functions

Logical gates (AND, NAND, OR, NOR, XOR, XNOR, NOT) made available as functions for ease of use in functional programming styles. An example, reducing an array to a single boolean value:

var gates = requrie('logic-gates');

[true, true, true].reduce(gates.and);  // true
[true, false, true].reduce(gates.and);  // false
[false, false, false].reduce(gates.and);  // false

You can also use them with currying/partial application or other functional styles:

var gates = require('logic-gates');

var andTrue = curry(gates.and)(a);

if (andTrue(b)) {
    console.log('a and b are true');
}

// Currying method
function curry(func) {
    return function(a) {
        return function(b) {
            return func(a, b);
        };
    };
}

Install

$ npm install [--save] logic-gates

Usage

The defined logical gate methods are fast, accurate, and work on any type of input.

var gates = require('logic-gates');

gates.and(true, false);  // false
gates.nand(true, false);  // true
gates.not.and(true, false);  // true

gates.or(true, false);  // true
gates.nor(true, false);  // false
gates.not.or(true, false);  // false

gates.xor(true, false);  // true
gates.xnor(true, false);  // false
gates.not.xor(true, false);  // false

gates.not(true);  // false
gates.not(false);  // true
