Javascript array splice() is an inbuilt method that changes the items of an array by removing or replacing the existing items and/or adding new items. The splice() method adds/removes items to/from an array and returns the removed item(s). It will return a new array. In the splice method, if you specify the different number of the item to insert than the number you’re removing, then the array will have a different length at the end of the call.

Javascript Array Splice Example

The splice method is similar to Array.prototype.slice, but unlike  slice() method it mutates the array it is called on. It also differs in that it can be used to add values to an array as well as remove them.

Now, let us see the syntax of javascript array splice() method.

array.splice(index, howmany, item1, ....., itemX)

So here the first parameter is the index of an array which means where to start the adding or to remove the item. The second parameter is howmany means from the start index how many indexes we need to cover from the starting index.

#javascript #array.prototype.splice #howmany
