I am running into an issue, I have a similar array of Strings in JS:
var myArray = ["bedroomone", "bedroomonetwo", "bathroom"];
And I would like to retrieve all the elements in the array that contains the keyword 'bedroom'. How can I achieve such result ?
I tried in different ways without getting the desired result. How should I proceed ?

var PATTERN = 'bedroom',
filtered = myArray.filter(function (str) { return str.indexOf(PATTERN) === -1; });
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); });
var bedrooms = myArray.filter(name => name.includes('bedroom'))
Improved Microfed's answer to this
var textToSearch = 'bedroom';
var filteredArray = myArray.filter((str)=>{
return str.toLowerCase().indexOf(textToSearch.toLowerCase()) >= 0;
});
Using JavaScript arrow function is much simpler
const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
const result = words.filter(word => word.length > 6);
console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]
// search using keyword from array
var keywordToSearch = 'Arslan'; // word to search
var keyword = keywordToSearch.toLowerCase();
var names = [{id: 1, name: 'Aqib'}, {id: 2, name: 'Arslan'}];
//search keyword from names array by name
var searchResult = names.filter(word => word.name.toLowerCase().indexOf(keyword) > -1);
console.log(searchResult);
// expected output: > Array [Object { id: 2, name: "Arslan" }]Using javascript arrow function 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);
};
