⚒️ Rules

* And or &&
* Input[]: Array (Size: Unlimited).
* Output: Boolean (true or false).
* Description: Do the Anding operation, if any value in Input[] has a value of (null, 0, false), it will return false, else it will return true.

* Or or ||
* Input[]: Array (Size: Unlimited).
* Output: Boolean (true or false).
* Description: Do the Oring operation, if all values in Input[] has a value of (null, 0, false), it will return false, else it will return true .

* Equal or ==
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Equal element two or not.

* NotEqual or =
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Not Equal to element two or not.

* Not or !
* Input[]: Array (Size: 1).
* Output: Boolean (true or false).
* Description: It takes an array of 1 input inverts its value. If it true it will return false and vice versa.

* GreaterThan or >
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Greater Than element two or not.

* LessThan or <
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Less Than element two or not.

* GreaterThanOrEqual or >=
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Greater Than or Equal element two or not.

* LessThanOrEqual or <=
* Input[]: Array (Size: 2).
* Output: Boolean (true or false).
* Description: It takes an array of 2 inputs to compare if element one Less Than or Equal element two or not.

💻Examples

`js
import { JsonLang } from '@jsonlang/core';
import { LogicRules } from '@jsonlang/logic';

const jsonLang = new JsonLang();

jsonLang.import(LogicRules);

jsonLang.execute( { "$R": "LessThan" , "$I": [10, 20] }, undefined, { sync: true } ); // true

// or for short
jsonLang.execute( { "$R": "<" , "$I": [10, 20] }, undefined, { sync: true } ); // true

// or use the async function
jsonLang.execute( { "$R": "<" , "$I": [10, 20] } )
.then(result => {
console.log(result); // true
});

🔌 Compatibility

This library uses Array.map and Array.reduce`, so it's not exactly Internet Explorer 8 friendly.
