Module "xform/swizzle"

swizzle

• swizzle<T>(order: PropertyKey[]): Transducer<T, any[]>
• swizzle<T>(order: PropertyKey[], src: Iterable<any>): IterableIterator<any[]>

• Transducer which performs value reordering on inputs using provided property order. Accepts arrays or objects as input, but always yields arrays.

  example

  [...swizzle([3,0,2,1], [[1,2,3,4], [10,20,30,40]])]
  // [ [ 4, 1, 3, 2 ], [ 40, 10, 30, 20 ] ]
  
  [...swizzle([0,0,1,1], [[1,2,3,4], [10,20,30,40]])]
  // [ [ 1, 1, 2, 2 ], [ 10, 10, 20, 20 ] ]
  
  [...swizzle(["z","x"], [{x: 1, y: 2, z: 3}])]
  // [ [ 3, 1 ] ]
