API

splitAt(string, index, options?)

string

Type: string

String to be split.

index

Type: number | number[]

One or more indices. A negative index is a 1-based position from the end of the string. For example, -1 is the index of the last place in the string. Duplicate indices are removed from the index array. A negative index and positive index that refer to the same position in the string are treated as duplicates.

options

Type: object

remove

Type: boolean
Default: false

Remove the chosen indices.

Similar to the default String#split behaviour.
