Splice
Splice allows us to remove items based upon their index position and can remove multiple items. If we run the following code with our baseball array…
baseballCards.splice(2, 1);
console.log( baseballCards );The console will report ‘Aaron’, ‘Ruth’, ‘Uecker’ because we asked the splice operation to start at index position 2, which was ‘Wagner’ and to remove 1 item.
We can also add items to our array using splice. Any values we put after the number of items to remove will be added to the array. Consider the following…
baseballCards.splice(2, 1, ‘Cobb’, ‘Fingers’);
console.log( baseballCards );The console will output ‘Aaron’, ‘Ruth’, ‘Uecker’, ‘Cobb’, ‘Fingers’. There are many JavaScript array methods available to us…
