What's the best way to query an array in javascript to get just the items from it I want?

Question

I have an array like this (with just over 3000 objects instead of the 3 here):

items = [{name:\'charlie\', age:\'16\'}, {name:\'ben\', age:\'18\'}, {name:\'s         


        

Answer 1

Get matched item and items using find() and filter() method

If you want first matched single item, use find() method which returns single object.

If you want all matched , use filter() method which returns array of objects.

let items = [{name:'charlie', age:'16'}, 
{name:'ben', age:'18'}, 
{name:'steve', age:'18'}]

let all = items.filter(item=> item.age==='18')
console.log(all);

let single = items.find(item=> item.age==='18')
console.log(single);
