Answer 1

You could also use the search() method

Finds the first substring match in a regular expression search.

(method) String.search(regexp: string | RegExp): number (+1 overload)

const filterList = (data, query) => {
        return data.filter(name => name.toLowerCase().search(query.toLowerCase()) !== -1);
      };

Answer 2

String.prototype.indexOf:

var PATTERN = 'bedroom',
    filtered = myArray.filter(function (str) { return str.indexOf(PATTERN) === -1; });

Regexp:

var PATTERN = /bedroom/,
    filtered = myArray.filter(function (str) { return PATTERN.test(str); });

String.prototype.includes (only in moderm browsers):

var PATTERN = 'bedroom',
    filtered = myArray.filter(function (str) { return str.includes(PATTERN); });

Answer 3

Improved Microfed's answer to this

var textToSearch = 'bedroom';
var filteredArray = myArray.filter((str)=>{
  return str.toLowerCase().indexOf(textToSearch.toLowerCase()) >= 0; 
});

Answer 4

var bedrooms = myArray.filter(name => name.includes('bedroom'))
