Filter Method

array.includes()

The filter() method determines whether a array contains specified element.

let fruits = [
    {title:"title 1", desc:"description 1"},
    {title:"headline 2", desc:"description 2"},
    {title:"title 3", desc:"description 3"}
];

let n = fruits.filter(f => {
    return f.title == 'title 1';
});


let n2 = fruits.filter(f => {
    return f.title.includes('title');
});
