return a value of array that have special name-CodePudding

Im new in react js and I get a problem with my array... I want to return a value of my array that have contain name and adress .and all value are string thi is my data that I need name :123, adress:12569

const array = [
  0: [ 'name','123' ],
  1: [ 'adress','12569'],
  2: ['family','4'],
];

CodePudding user response：

You can run loop on the array and assign key-value for each of the array items.

const array = [
  ['name', '123'],
  ['adress', '12569'],
  ['family', '4'],
];
const res = {};
array.forEach((item) => {
  res[item[0]] = item[1];
})

console.log(res);

CodePudding user response：

In this case, you should use an Object.

const foo = {
    name: '123',
    adress: 'bar',
    family: '4',
}

So, to access the propertys:

console.log(foo.name); // 123
console.log(foo.adress); // bar
console.log(foo.family); // 4

But if you are getting this information as an array, you can always transform it into an object.

CodePudding user response：

It would make more sense for that data to be combined into a single object rather than a series of nested arrays, and then use find to locate the object that matches the query.

const data = [
  { name: 'Bob', address: '999 Letsbe Avenue', family: 4 },
  { name: 'Sally', address: '8 Treehouse Lane', family: 0 },
  { name: 'Joan', address: '85 Long Terrace', family: 6 }
];

// Accepts the data array, and a query object
function findFamily(data, query) {

  // Iterate through the data array to `find`
  return data.find(obj => {

    // Split the query into key/value pairs
    const queryEntries = Object.entries(query);

    // And return only those objects where the
    // object key/value matches the query key/value
    return queryEntries.every(([ key, value ]) => {
      return obj[key] === value;
    });

  // And if there are no matches return 'No match'
  }) || 'No match';
}

console.log(findFamily(data, {
 name: 'Bob',
 address: '999 Letsbe Avenue',
 family: 0
}));

console.log(findFamily(data, {
 address: '999 Letsbe Avenue',
 family: 4
}));

console.log(findFamily(data, {
 name: 'Sally'
}));
