Module slice

Callable

• slice<T>(array: ArrayLike<T>, options?: IOptions): T[]

• Create a slice of an array subject to an optional step.

  throws

  An exception if the slice step is 0.

  Complexity

  Linear.

  Undefined Behavior

  A start, stop, or step which is non-integral.

  Example

  import { ArrayExt } from '@lumino/algorithm';
  
  let data = [0, 3, 4, 7, 7, 9];
  ArrayExt.slice(data);                         // [0, 3, 4, 7, 7, 9]
  ArrayExt.slice(data, { start: 2 });           // [4, 7, 7, 9]
  ArrayExt.slice(data, { start: 0, stop: 4 });  // [0, 3, 4, 7]
  ArrayExt.slice(data, { step: 2 });            // [0, 4, 7]
  ArrayExt.slice(data, { step: -1 });           // [9, 7, 7, 4, 3, 0]

  Type parameters

  • T

  Parameters

  • array: ArrayLike<T>

    The array-like object of interest.

  • Default value options: IOptions = {}

    The options for configuring the slice.

  Returns T[]

  A new array with the specified values.
