Write a function that takes Season number and episode number as input and gives all the information about that particular episode as output

After taking inputs from the user as season number and episode number, it doesn't give output as the information about that particular episode

let BigBang =  { 
    "_embedded": {
        "episodes": [
          {
            "id": 2913,
            "name": "Pilot",
            "season": 1,
            "number": 1,
            "airdate": "2007-09-24",
            "airtime": "20:30",
            "airstamp": "2007-09-25T00:30:00+00:00",
            "runtime": 30,


            "_links": {
              "self": {
                "href": "http:\/\/api.tvmaze.com\/episodes\/2913"
              }
            }
          },
          {
            "id": 2914,
            "name": "The Big Bran Hypothesis",
            "season": 1,
            "number": 2,
            "airdate": "2007-10-01",
            "airtime": "20:30",
            "airstamp": "2007-10-02T00:30:00+00:00",
            "runtime": 30,
            "image": {
              "medium": "http:\/\/static.tvmaze.com\/uploads\/images\/medium_landscape\/4\/12369.jpg",
              "original": "http:\/\/static.tvmaze.com\/uploads\/images\/original_untouched\/4\/12369.jpg"
            },
       }



    let season = prompt('Enter Season number');                               
    let number = prompt('Enter Episode number');                            
    let AllInfo = (season,number) => {                                   
        for(let current in BigBang._embedded.episodes) {                    
            if(BigBang._embedded.episodes[current].season === season) {                                              
                if(BigBang._embedded.episodes[current].number === number) { 
                let Detail = BigBang._embedded.episodes[current];
                    alert(Detail);
                }
            }
        }                            
    AllInfo(season,number);                         
    }

Try using .find instead, it'll make the code a lot cleaner:

    let BigBang = {
      "_embedded": {
        "episodes": [{
            "id": 2913,
            "name": "Pilot",
            "season": 1,
            "number": 1,
            "airdate": "2007-09-24",
            "airtime": "20:30",
            "airstamp": "2007-09-25T00:30:00+00:00",
            "runtime": 30,
            "_links": {
              "self": {
                "href": "http:\/\/api.tvmaze.com\/episodes\/2913"
              }
            }
          },
          {
            "id": 2914,
            "name": "The Big Bran Hypothesis",
            "season": 1,
            "number": 2,
            "airdate": "2007-10-01",
            "airtime": "20:30",
            "airstamp": "2007-10-02T00:30:00+00:00",
            "runtime": 30,
            "image": {
              "medium": "http:\/\/static.tvmaze.com\/uploads\/images\/medium_landscape\/4\/12369.jpg",
              "original": "http:\/\/static.tvmaze.com\/uploads\/images\/original_untouched\/4\/12369.jpg"
            },
          }
        ]
      }
    }
    //const inputSeason = prompt('Enter Season number');
    const inputSeason = 1;
    //const inputNumber = prompt('Enter Episode number');
    const inputNumber = 2;

    const foundEpisode = BigBang._embedded.episodes.find(({ season, number}) => {
      return season === inputSeason && number === inputNumber;
    });
    if (foundEpisode) console.log(foundEpisode);
    else console.log('No matching season/number found!');
