Skipping an item in an array during the filtering process

I encountered an issue while trying to filter an array using a specific method. However, I noticed that one value is being skipped in the process!

function customFilterArray(array, remove){
    
    console.log('Length of Array:',array.length)
    console.log("Array:",array);
    console.log('Values to Remove:',remove);
    console.log('------');
    array.forEach(function(element){       
       if(remove.includes(element.serial)){
           console.log('Item to be removed:',element);
           array.splice(array.indexOf(element),1);
       }       
    });
    
    console.log('New Length of Array:',array.length);
    return array;
}

I am confused as to why this anomaly is occurring. Could someone kindly provide some insights on this matter?

Below is the console output for reference:

Answer №1

If you are looking to avoid modifying the initial array, filter can be utilized:

function filterOutArrayValues(array, valuesToRemove){
    return array.filter(element => !valuesToRemove.includes(element.id));
}
