const data = fs.readFileSync('./movies.JSON');
data.toString();
var obj = JSON.parse(data);
console.log(Object.values(obj.moviesList));
This is my js file. This prints all keys and pairs of my JSON file. I am trying to access the nested array in the JSON file. I have tried console.log(Object.values(obj.moviesList.actors==="206'));
And a bunch of other variations.
"moviesList":[
{
"movieId": 4192148,
"title": "Highly Functional",
"actors": [
3188187,
3306943,
132257,
47265
]
},
here is a small snippet of my JSON file containing nested arrays.
I want to start out by printing out all movie Id's that have an actor whose id is 206.
If you are scanning a nested array, here's one way to about that using includes to check the actors array.
const moviesList = [{
"movieId": 4192148,
"title": "Highly Functional",
"actors": [
3188187,
3306943,
132257,
47265
]
},
{
"movieId": 11111,
"title": "Highly Functional2",
"actors": [
3188187,
3306943,
206,
47265
]
},
{
"movieId": 11112,
"title": "Highly Functional3",
"actors": [
3188187,
3306943,
206,
47265
]
}
];
let matches = [];
for (const movie of moviesList) {
const { actors, movieId } = movie;
if (actors.includes(206)) {
matches.push(movieId);
}
}
console.log(matches);
// Another format
matches = moviesList
.filter(({ actors }) => actors.includes(206))
.map(({ movieId }) => movieId)
console.log(matches);
