Note: splice() can only remove consecutive items. Use splice() in this way – arr.splice(1, 2, "new item 1", "new item 2", "new item 3", "new item 4") Let’s say we want to add these 4 items – new item 1, new item 2, new item 3, new item 4. ![]() Removing 2nd and 3rd item = removing 2 items from 1st index. We just want to add two new items at index 2.įinal array will appear like this – Example 3 – Removing 2nd and 3rd item and adding 4 items at their place This is because we do not want to remove any item. You can see that we have used 0 as second parameter. You should use the function like this – arr.splice(2, 0, "item 5", "item 6") It means you want to add 2 items (let’s say – item 5 and item 6) at 2nd index of array. Our final array will become – Example 2 – You want to add 2 items at 3rd position Use splice() like this – arr.splice(2, 1) įirst parameter is index so we used 2 and second parameter is number of items so we used 1. Suppose the given array is – var arr = Example 1 – You want to remove 3rd itemģrd item means, array index 2, because indexes starts from 0.
