Data Types

Primitive Value

• string
• blob
• int64
• float64
• bool
• null
• list of primitive value // []*primitive_value
  • 0-indexed
• map of primitive value // map[string]*primitive_value
• list of interface // Json Array []interface{}
• map of interface // Json Object map[string]interface{}
• undefined

Object Types

Error

• new Error(message, )
• name: "Error", "RangeError", "InternalError", "ReferenceError", "SyntaxError", "TypeError"

Time

• new Time() // create a time object. The value is set to current timestamp
• new Time(epoch) // create a time object. The epoch could be second or millisecond
• new Time(relativeTime) // create a time object from a relative time
• new Time(layout, value, )

Time Layouts:

  ANSIC       = "Mon Jan _2 15:04:05 2006"
	UnixDate    = "Mon Jan _2 15:04:05 MST 2006"
	RubyDate    = "Mon Jan 02 15:04:05 -0700 2006"
	RFC822      = "02 Jan 06 15:04 MST"
	RFC822Z     = "02 Jan 06 15:04 -0700" // RFC822 with numeric zone
	RFC850      = "Monday, 02-Jan-06 15:04:05 MST"
	RFC1123     = "Mon, 02 Jan 2006 15:04:05 MST"
	RFC1123Z    = "Mon, 02 Jan 2006 15:04:05 -0700" // RFC1123 with numeric zone
	RFC3339     = "2006-01-02T15:04:05Z07:00"
	RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"
	Kitchen     = "3:04PM"
	// Handy time stamps.
	Stamp      = "Jan _2 15:04:05"
	StampMilli = "Jan _2 15:04:05.000"
	StampMicro = "Jan _2 15:04:05.000000"
	StampNano  = "Jan _2 15:04:05.000000000"
	DateTime   = "2006-01-02 15:04:05"
	DateOnly   = "2006-01-02"
	TimeOnly   = "15:04:05"

• location is optional
• If the name is "" or "UTC", the timezone is set to "UTC". Otherwise, the name is taken to be a location name corresponding to a file in the IANA Time Zone database, such as "America/New_York"
  • Lambda
• simple expression: (x, y) ⇒ x+y

Block Statements

The parament support object/array destructuring: (obj) ⇒ obj.field1 + obj.field2 OR ({field1, field2})

(x, y) => {
  let a = x + 1
  return a + y
}  // explicit return is required

the lambda parameter support object/array destructuring:

  // obj is a map/object type variable
  (obj) => obj.field1 + obj.field2
  // OR
  ({field1, field2}) => field1 + field2

FplTable

• new Table(col1,col2,…​)
• Columns
• Rows

FplMetric

• from, to
• interval
• dimensions
• Metrics

FplAlert

Tuple: list of Data Types or Object Types

Map: map of Data Types or Object Types
