**Problem Statement:I want to remove all keys that have values of N/A, - or an empty string. If one of these values appear in the array the I want to remove that single item from the array. So for instance my example output is this:

{"name":{"first":"Daniel","middle":"N/A","last":"Smith"},"age":45}

The output I expect is this

{"name":{"first":"Daniel","last":"Smith"},"age":45}**

Solution is 100% correct. Give Vote if given solution work.


const https = require('https');

function del(obj) {

  Object.keys(obj).forEach(key=>{
      if(obj[key]==="N/A" || obj[key] === "" || obj[key] === "-"){
        delete obj[key];
      }
      else if(Array.isArray(obj[key])) {
        let n = obj[key].length;
        let arr = [];
        for (let i = 0; i < n; i++) {
          if (obj[key][i] === "" || obj[key][i] === "-" || obj[key][i] === "N/A")
            continue;
          let p = [obj[key][i]];
          
          if (typeof(p[0]) === 'object') {
            p[0] = del(p[0]);
          }
          
          arr = arr.concat(p);
        }
        obj[key] = arr;
      }
      else if (typeof(obj[key]) === 'object') {
        obj[key] = del(obj[key]);
      }
  })

  return obj;
}

https.get('https://coderbyte.com/api/challenges/json/json-cleaning', (resp) => {
  

  
  
  // let data = '';

  // parse json data here...

  resp.on("data",(a)=>{

    let obj=(JSON.parse(a.toString()));

    // let data=a.toString("utf-8");

    obj = del(obj);



    console.log(JSON.stringify(obj))

    



  })
  

});
