How to apply a conditional to forEach loop in Javascript?

Question

function createDOMNodes( page ) {

    const currentArray = page === 'result' ?
        resultsArray :
        Object.values( favorites );

    // console.log( 'currentArray' , page , currentArray );
    
    currentArray.latest_photos.forEach( (result) => { // do something } );
}

The problem is that there is no latest_photos in the favorites object, I just want to loop the currentArray.forEach when the page parameter is 'favorites'

how can I do that?

It want to switch between different properties when the page is changed. It works fine when I remove the latest_photos property.

Is there a way to Loop through a different array when the page is changed

Is there a reason you're using .forEach instead of for( of ) ? — Dai

In the conditional, take the latest_photos instead of the entire resultsArray

const currentArray = page === 'result'
  ? resultsArray.latest_photos
  : Object.values(favorites);

currentArray.forEach((result) => { // do something }

but this affects my fetch statement, it only returns only 4 photos , for some reason , instead of 10 . is there a reason for that?

There is no fetch in your question..? What code are you referring to? That sounds like a completely separate issue
