External module "array/intersection"

intersection

• intersection<T>(base: T[], inclusion: TInclusion, allEquals?: boolean): T[]
• intersection<T>(base: Set<T>, inclusion: TInclusion, allEquals?: boolean): Set<T>

• Intersection

  Gets the intersection of the two arrays or sets

  ---

  Example:

  import { intersection } from "@thalesrc/js-utils/array";
  
  const base = ["a", "b", "c", "d", "a", "b", "c", "d"];
  
  intersection(base, ["a", "b", "x"]); // ["a", "b", "a", "b"]
  intersection(base, ["a", "b", "x"], false); // ["a", "b"]

  Array Prototype Example:

  import "@thalesrc/js-utils/array/proto/intersection";
  
  const base = ["a", "b", "c", "d", "a", "b", "c", "d"];
  
  base.intersection(["a", "b"]); // ["a", "b", "a", "b"]

  Set Prototype Example:

  import "@thalesrc/js-utils/set/proto/intersection";
  
  const base = new Set(["a", "b", "c", "d"]);
  
  base.intersection(["a", "b"]); // Set(["a", "b"])

  Type parameters

  • T

  Parameters

  • base: T[]

    Base Set or Array

  • inclusion: TInclusion

    Set or Array to include its values

  • Optional allEquals: boolean

    By default all the same items encountered in the inclusion will be included, set this argument as false to get real intersection

  Returns T[]

  Intersection of base and inclusion

• Type parameters

  • T

  Parameters

  • base: Set<T>

  • inclusion: TInclusion

  • Optional allEquals: boolean

  Returns Set<T>
