Export assignment funseqAsync

• funseqAsync(f0: VariadicFunction, f1: BinaryFunction, ...f: Array<BinaryFunction>): PipelineFunction

• Function sequence.

  Parameters

  • f0: VariadicFunction

    first function to evaluate

  • f1: BinaryFunction

    second function to evaluate

  • Rest ...f: Array<BinaryFunction>

    remaining functions to evaluate in sequential order

  Returns PipelineFunction

  pipeline function

  Example

  function a( x, next ) {
      setTimeout( onTimeout, 0 );
      function onTimeout() {
          next( null, 2*x );
      }
  }
  
  function b( x, next ) {
      setTimeout( onTimeout, 0 );
      function onTimeout() {
          next( null, x+3 );
      }
  }
  
  function c( x, next ) {
      setTimeout( onTimeout, 0 );
      function onTimeout() {
          next( null, x/5 );
      }
  }
  
  var f = funseqAsync( a, b, c );
  
  function done( error, result ) {
      if ( error ) {
          throw error;
      }
      console.log( result );
      // => 3
  }
  
  f( 6, done );
