When working with TinyGo be ready to change certain coding conventions that are common place in high level languages, such as Go. Memory is an object.

It is prefferable to avoid the garbage collector too, as it will slow down your program noticeably. To do this avoid using the make built-in.

These are some things to avoid doing with TinyGo

// TinyGo No-No's
slice := make([]int,8)
for {
    // allocating memory in a for loop.
    // Avoid slices in general.
    anotherSlice := []int{1,2,3}
}

• Declaring arrays and passing arrays as slices to functions

  array := [...]int{1,2,3}
  // array[:] is the slice of all elements in array
  sliceFunc(array[:])
  // same as
  sliceFunc(array[0:len(array)])

• Declaring variables outside of for scope and using the 3 statement for to iterate.

  var iter = [3]int{1,2,3}
  var j int
  
  for i:=0; i<len(iter); i++ {
      
      j = mapFunc(i, iter[i])
      
      iter[i] = j*j
  }
