Drive from Snoqualmie Home in Woodlands to Bellevue.

• Garage: types: char, string, bool, numeric
• our car: constants: const size int64 = 1024
• Neighbour car: variables: var msg string = “Hi world”
• Safeway path: shortcut: msg := “hi”
• Crossing: string: str := “hi”, str := Hi // multiline
• Swenson Drive: number: num := 3, var num float32 = 22.7
• Traffic light: array: nums := [3]int{1, 2, 4} // fixed length
• Parkway: slice: nums := []int{1, 2, 4} // variable length
• Jacobia: pointer: p := &i (p points to i’s memory location); i = *p (read i through pointer p)
• 30 zone: conditional: if day == “sun” { rest() } else if day == “mo” { start() } else { work() }
• hospital: statements in if: if _, err := doThing(); err != nil {fmt.Println(“Oh!”)}
• I90 ramp: conversions: f := float(3)
• ramp lights: switch: switch day {case “sun”: fallthrough case “sa”: rest() default: work() }
• I90: for loop: for count := 0; counter <= 10; count++ {do(count)}
• Preston: for range loop: entry := []str{“A”, “B”}: for i, val := range entry{(i, val)}
• High Point: while: n := 0; x := 42; for n != x{ n := guess() }
• Highlands: lambdas: myFunc := func() bool {return x > 10}
• Downtown: multiple return values: a,b, := getMsg() (a string, b string){return “hi”, “u”}
• Best Buy: named return values: func split(sum int) (x, y int) { x=sum; y=sum-1; return }
• REI HQ: importing: import “fmt”
• Lake Sammamish: aliases: import r “math/rand”
• Lakemont: package: package hello // every file starts with package
• Eastgate: exporting names: begin w/ capital letter e.g., fmt.Println(“hi”)
• 405: goroutine: channels are concurrency safe
• Bellevue Way Ramp: buffered channels: limit a channel’s amount
• Lightrail: closing channels: v, ok <- ch // closed if ok == false
• Bellevue Way: waitgroup: waits for goroutine to finish
• Outer route: defer: skips running function until outer func runs // @decorator in Python
• 112th: defer func(){fmt.Println(“Done”)} () fmt.Println(“Working”)
• 929: structs: v := Vertex{x:1, y:2} // dict-ish
• boom gate: receivers: func (v Vertex) Abs() float {…}; v.Abs() // def input name return
• parking: mutations: func (v *Vertex) Scale (f float) {…}; v.Scale(.5) // mutation by def receiver as pointer
• door: interface: type Shape interface {Area() float64}
  • walk: method: func (r Rectangle) Area() float64 {return r.Length * r.Width}
  • stairs: struct: type Rectangle struct {length, width float64} // implements shape
• elevator: var r Shape = Rectangle{length:3, width:4}; fmt.Println(r.Area()) // 12
