Answer 1

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); });
