find an entry in the events array that has a given url in javascript

You can use the find or filter method of the array to find an entry that has a given url. Here is an example using the find method:


index.tsx
const events = [
    { id: 1, url: 'https://example.com/event1' },
    { id: 2, url: 'https://example.com/event2' },
    { id: 3, url: 'https://example.com/event3' }
];

const urlToFind = 'https://example.com/event2';
const foundEvent = events.find(event => event.url === urlToFind);

console.log(foundEvent); // Output: { id: 2, url: 'https://example.com/event2' }
366 chars
11 lines

In the example above, we have an array of events that contains objects with id and url properties. We want to find an event that has a specific url, so we use the find method to iterate over the array and return the first event that has a url property that matches urlToFind.

The find method returns the found event object or undefined if no match is found.

You can also use the filter method to find all entries with a given url. Here is an example:


index.tsx
const events = [
    { id: 1, url: 'https://example.com/event1' },
    { id: 2, url: 'https://example.com/event2' },
    { id: 3, url: 'https://example.com/event2' }
];

const urlToFind = 'https://example.com/event2';
const matchingEvents = events.filter(event => event.url === urlToFind);

console.log(matchingEvents); // Output: [{ id: 2, url: 'https://example.com/event2' }, { id: 3, url: 'https://example.com/event2' }]
424 chars
11 lines

In this example, we use the filter method to return an array of all events that have a url property that matches urlToFind. The filter method returns a new array containing all the matching events.
