Filter object containing array of object

Question

I would like to filter my data depending on a typed keyword.

let keyword = '-pre';

let data = {
  'Basic': [{
    name: 'a-basic'
  }, {
    name: 'b-basic'
  }, {
    name: 'c-basic'
  }],
  'Premium': [{
    name: 'a-pre'
  }, {
    name: 'b-pre'
  }, {
    name: 'c-pre'
  }],
  'Extra': [{
    name: 'a-ext'
  }, {
    name: 'b-ext'
  }, {
    name: 'c-ext'
  }],
};

Output

'Premium': [{name: 'a-pre'}, { name: 'b-pre'}, { name: 'c-pre'}]

My try

lodash.forEach(data, (card) => {
  card = card.filter(o => {
    return Object.keys(o).some(k => {
      return typeof o[k] === 'string' && o[k].toLowerCase().includes(keyword.toLowerCase());
    });
  });
})

But it does not work.The difficulty for me is that the filtering must happen on the nested object keys contained in each array.

card is lost. Do sth like data[card]=card.filter

 var result={};
 Object.keys(data).forEach(key => {
   result[key] = data[key].filter(o => {
       return Object.keys(o).some(k =>typeof o[k] === 'string' && o[k].toLowerCase().includes(keyword.toLowerCase()));
  });
})

superfluous curly brackets and return statements in arrow functions, no explanations.

Because this is object you can use reduce() on Object.keys() instead and then inside use every() to check for keyword.

let keyword = '-pre';

let data = {"Basic":[{"name":"a-basic"},{"name":"b-basic"},{"name":"c-basic"}],"Premium":[{"name":"a-pre"},{"name":"b-pre"},{"name":"c-pre"}],"Extra":[{"name":"a-ext"},{"name":"b-ext"},{"name":"c-ext"}]}

var result = Object.keys(data).reduce(function(r, e) {
  var check = data[e].every(o => o.name.indexOf(keyword) != -1);
  if(check) r[e] = data[e]
  return r;
}, {})

console.log(result)
