Find specific JSON key and return its value in Javascript-CodePudding

I have some JSON from an API which I am logging in the console. This is easy for something like the id where I can do this...

let movieID = out.id;
console.log(movieID)

But how can I also return the 'name' of the person whose job is specifically 'Director' from JSON example like this? Basically I need to do something like 'if someone has the JOB of DIRECTOR, log their name to the console.

{
    "id": 37291,
    "credits": {
        "crew": [
            {
                "name": "John Smith",
                "job": "Producer"
            },
            {
                "name": "Mary Jones",
                "job": "Director"
            }
        ]
    }
}

You can get the list of the crew, like you described above. Then find the first entry in that list where the job equals "Director" and put it in a variable:

let director = out.credits.crew.find(member => member.job == "Director");

You can then log the data, as you did for the movie itself.

CodePudding user response：

Something like this would do literally what you asked which was to console log out the names

credits.crew.foreach((crewMember) => {
    if (crewMember.job == 'Director') {
      console.log(crewMember.name)
    }
  })

Use underscore:

_.filter(credits.crew, (key) => key.job === 'Director')

That will give you all the keys with that value. Trust me you should use underscore or lodash because objects can get super tricky and it saves you a ton of time.
