💻Examples

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.
