It starts from the index, removes as many elements as specified by elementCountForRemoval, and puts the replacements starting from index position. ## Method Signature ``` ArraySplice(array=[modifiablearray], index=[Integer], elementCountForRemoval=[Integer], replacements=[array]) ``` ### Arguments | Argument | Type | Required | Description | Default | | ------------------------ | ----------------- | -------- | --------------------------------------------- | ------- | | `array` | `modifiablearray` | `true` | The array to splice | | | `index` | `Integer` | `true` | The initial position to remove or insert from | | | `elementCountForRemoval` | `Integer` | `false` | The number of elemetns to remove | `0` | | `replacements` | `array` | `false` | An array of elements to insert | | ## Examples ### arraySplice inserting replacements at position 2 while removing 0 elements [Run Example](https://try.boxlang.io/?code=eJzLzc8ryShWsFWIVuDiVPJKzFPSAdK%2BiUXJGWCWY0FRZg6Y5VWal6rEFWvNlVmSmgvSABRzS00CCyUWFSVWBhfkZCanaijkgo3UUTDSUTDQUQCr1rTmKi8CslJKcwtgCkCCAGPBI3Y%3D) ```java months = [ "Jan", "March", "April", "June" ];
