How do I filter an array of objects by keyword using LoDash?

Question

Let's say I have an array of objects like this:

[{
  away: "Seattle Seahawks",
  home: "Kansas City Chiefs",
},
{
  away: "Houston Texans",
  home: "San Francisco 49ers",
},
{
  away: "Dallas Cowboys",
  home: "Los Angeles Rams",
}]

Requirements:

Search every object and for the keyword 49er and have it return object #2.

Search every object for the keyword cow and have it return object #3.

Search every object for the keyword an and have it return all three objects.

What would be the best way to achieve this in lodash? Thanks!

Answer 1

My solution with _.flow:

const my_arr = [{
  away: "Seattle Seahawks",
  home: "Kansas City Chiefs",
},
{
  away: "Houston Texans",
  home: "San Francisco 49ers",
},
{
  away: "Dallas Cowboys",
  home: "Los Angeles Rams",
}]

function flowFilter(array, substr) {
    return _.filter(array, _.flow(
    _.identity,
    _.values,
    _.join,
    _.toLower,
    _.partialRight(_.includes, substr)
  ));
}

const one = flowFilter(my_arr, '49er');
const two = flowFilter(my_arr, 'cow');
const three = flowFilter(my_arr, 'an');

console.log('one', one);
console.log('two', two);
console.log('three', three);

No need of lodash library use native JavaScript methods.

var data = [{
  away: "Seattle Seahawks",
  home: "Kansas City Chiefs",
}, {
  away: "Houston Texans",
  home: "San Francisco 49ers",
}, {
  away: "Dallas Cowboys",
  home: "Los Angeles Rams",
}];

console.log(
  // filter the array
  data.filter(function(v) {
    // get all keys of the object
    return Object.keys(v)
    // iterate and check for any object property value cotains the string
    .some(function(k) {
      // convert to lowercase(to make it case insensitive) and check match
      return v[k].toLowerCase().indexOf('49ers') > -1;
    })
  })
);

console.log(
  data.filter(function(v) {
    return Object.keys(v).some(function(k) {
      return v[k].toLowerCase().indexOf('an') > -1;
    })
  })
);
