Export assignment funseq

• funseq(...fcn: Array<Function>): Function

• Returns a pipeline function.

  Notes

  • Starting from the left, the pipeline function evaluates each function and passes the result as an argument to the next function. The result of the rightmost function is the result of the whole.
  • Only the leftmost function is explicitly permitted to accept multiple arguments. All other functions are evaluated as unary functions.

  throws

  must provide more than one argument

  Parameters

  • Rest ...fcn: Array<Function>

    functions to evaluate in sequential order

  Returns Function

  pipeline function

  Example

  function a( x ) {
      return 2 * x;
  }
  
  function b( x ) {
      return x + 3;
  }
  
  function c( x ) {
      return x / 5;
  }
  
  var f = funseq( a, b, c );
  
  var z = f( 6 );
  // returns 3
