How can I remove a specific item from an array

0 votes

I have an array of numbers and I'm using the .push() method to add elements to it.

Is there a simple way to remove a specific element from an array?

I'm looking for the equivalent of something like:

array.remove(number);

I have to use core JavaScript.

Hello @kartik,

Find the index of the array element you want to remove using indexOf, and then remove that index with splice.

The splice() method changes the contents of an array by removing existing elements and/or adding new elements.

const array = [2, 5, 9];

console.log(array);

const index = array.indexOf(5);
if (index > -1) {
  array.splice(index, 1);
}

// array = [2, 9]
console.log(array); 

The second parameter of splice is the number of elements to remove. Note that splice modifies the array in place and returns a new array containing the elements that have been removed.

Hope it helps!!
Thank you!
