Tests:

  • Chain

     
    _.chain(data).filter(f => f.a === 'a').filter(f => f.b > 50000).filter(f => f.b + 1 === 2).map(f => f.a).filter(f => f === 'a').value()

  • Native (with &&)

     
    data.filter(f => f.a === 'a' && f.b > 50000 && f.b + 1 === 2).map(f => f.a).filter(f => f === 'a')

  • Native (without &&)

     
    data.filter(f => f.a === 'a').filter(f => f.b > 50000).filter(f => f.b + 1 === 2).map(f => f.a).filter(f => f === 'a')

  • Flow

     
    fp.flow(
      fp.filter(f => f.a === 'a'),
      fp.filter(f => f.b > 50000),
      fp.filter(f => f.b + 1 === 2),
      fp.map(f => f.a),
      fp.filter(f => f === 'a')
    )(data)
