Method values bind the receiver at creation; method expressions require you to pass the receiver explicitly.
c := Counter{v: 0}
p := &c
valM := c.Add
ptrM := p.AddPtr
#golang #programming
slices.Sort sorts in-place and preserves the slice's underlying array (no reallocation).
s := []int{3, 1, 2}
before := &s[0]
slices.Sort(s)
after := &s[0]
// same underlying array: true

An interface value is nil only when both its dynamic type and its value are nil.
type S struct{}
var p *S
var i interface{} = p

That moment when a riddle finally clicks after being stuck is unbeatable! Riddlance is such a fun brain teaser—totally worth a try!

Spot the bug:
b := make([]int, 3)
for i := 0; i+3 <= len(d); i++ {
copy(b, d[i:i+3])
res = append(res, b[:])
}

append(s, s...) copies the src's pre-append elements, so appending a slice to itself uses the original contents.
s := []int{1, 2, 3}
t := append(s, s...)

delete on a nil map is a no-op and reads return the zero value.
var m map[string]int
v, ok := m["x"]
delete(m, "x")
// 0 false 0 true
#golang #programming
Embedding a pointer type (*T) promotes both T's value-receiver and pointer-receiver methods.
func (A) Val() string { return "Val" }
func (*A) Ptr() string { return "Ptr" }
type B struct{ *A }
type C struct{ A }

A labeled continue jumps to the labeled loop's post statement (if any), then re-evaluates its condition.
Outer:
for i := 0; i < 3; i++ {
for j := 0; j < 3; j++ {
if j == 1 { continue Outer }
fmt.Printf("i=%d j=%d\n", i, j)
}
}

Method values bind the receiver at creation; method expressions need the receiver passed on each call.
t := T{v:1}
mv := t.Show
me := T.Show
t.v = 2
#golang #programming
In for-range, each iteration gets a fresh loop variable, so closures created inside the loop capture distinct values.
for _, v := range vals {
funcs = append(funcs, func() int { return v })
}

append([]T(nil), s...) clones a slice; append(s, x) may reuse and mutate s's backing array.
s := arr[1:3] // [2,3]
b := append([]int(nil), s...)
c := append(s, 9)
