Match value of variable to object array

Question

i'm trying to match the value of variable to an object array. the last if statement is what i'm struggling with. anything helps thanks in advance.

function getPage(){
    let pageActual = window.location.href;
    console.log(pageActual);

    let pageName = /500(.*)/;
    let EventName = pageName.exec(pageActual); // this creates the event name based on the event url you're currently on.
    console.log(EventName[1]);
const events2020v2 = [

{event:"example1", Date:'February 19, 2020'},
{event:"test2.html", Date:'February 11, 2020'},
{event:"example3", Date:'February 19, 2020'},
{event:"/test2.html", Date:'February 19, 2020'},
{event:"example4", Date:'February 19, 2020'}




];
// below im attempting to match the eventName to a value in the object above.
if(events2020v2.event.indexOf(EventName.value)){
         console.log('something')
     }

So .indexOf() works a bit differently. I suggest for this scenario .find() instead.

The indexOf() method returns the first index at which a given element can be found in the array, or -1 if it is not present.

The find() method returns the value of the first element in the provided array that satisfies the provided testing function.

Take a look at my example for your case:

const EventName = {
  value: 'test2.html'
};

const events2020v2 = [
   {event:"example1", Date:'February 19, 2020'},
   {event:"test2.html", Date:'February 11, 2020'},
   {event:"example3", Date:'February 19, 2020'},
   {event:"/test2.html", Date:'February 19, 2020'},
   {event:"example4", Date:'February 19, 2020'}
];

const found = events2020v2.find(e => e.event === EventName.value);

if (found) {
  console.log('found', found);
}

I hope that helps!

Thanks so much, this works. – Eddiejm007 Feb 20 '20 at 17:01 — Eddiejm007, Feb 20 '20 at 17:01
