data := array.Get(arrData, "b.d.e")
// output: eee

data := array.Get(arrData, "b.dd.1")
// output: ddddd

data := array.Get(arrData, "b.hh.3335.qq2")
// output: qq2ddddd

data := array.Get(arrData, "b.kJh21ay.Hjk2", "defValString")
// output: fccDcc

data := array.Get(arrData, "b.kJh21ay.Hjk23333", "defValString")
// output: defValString

Examples

• Exists data

var res bool = array.New(arrData).Exists("b.kJh21ay.Hjk2")
// output: true

var res bool = array.New(arrData).Exists("b.kJh21ay.Hjk12")
// output: false

• Get data

var res any = array.New(arrData).Get("b.kJh21ay.Hjk2")
// output: fccDcc

var res any = array.New(arrData).Get("b.kJh21ay.Hjk12", "defVal")
// output: defVal

• Find data

var res any = array.New(arrData).Find("b.kJh21ay.Hjk2")
// output: fccDcc

var res any = array.New(arrData).Find("b.kJh21ay.Hjk12")
// output: nil

• Use Sub to Find data

var res any = array.New(arrData).Sub("b.kJh21ay.Hjk2").Value()
// output: fccDcc

var res any = array.New(arrData).Sub("b.kJh21ay.Hjk12").Value()
// output: nil

• Use Search to Find data

var res any = array.New(arrData).Search("b", "kJh21ay", "Hjk2").Value()
// output: fccDcc

var res any = array.New(arrData).Search("b", "kJh21ay", "Hjk12").Value()
// output: nil

• Use Index to Find data

var res any = array.New(arrData).Sub("b.dd").Index(1).Value()
// output: ddddd

var res any = array.New(arrData).Sub("b.dd").Index(6).Value()
// output: nil

• Use Set to set data

arr, err := array.New(arrData).Set("qqqyyy", "b", "ff", 222)
// arr.Get("b.ff.222") output: qqqyyy

• Use SetIndex to set data

arr, err := array.New(arrData).Sub("b.dd").SetIndex("qqqyyySetIndex", 1)
// arr.Get("b.dd.1") output: qqqyyySetIndex

• Use Delete to delete data

arr, err := array.New(arrData).Delete("b", "hh", 2225)
// arr.Get("b.hh.2225") output: nil

• Use DeleteKey to delete data

arr, err := array.New(arrData).DeleteKey("b.d.e")
// arr.Get("b.d.e") output: nil
