About Go:

• Go is a statically types language.
  
• tall varibles have assingned types.
  
• you can set types explicitly or implicitly.
  

Datatypes:

• bool - true, false
• string - collection of characters
• integers - uint8, uint16, uint32, uint64 int8, int16, int32, int64

aliases can be used for these datatype : byte, uint, int, uintptr

• float - float32, float64
• complex (real and imaginary) - complex64, complex128

Data collections :

• arrays
• slices
• maps
• structs

language organization :

• functions
• interfaces
• channels

Data management :

• pointers

You can also create your own datatype.

Math Operators

• += sum
• -+ difference
• *= product
• /+ quotient
• % remainder
• & bitwise AND
• | bitwise OR
• ^ bitwise XOR
• &^ bit clear
• << left shift
• >> right shift

Memory management

• Go runtime is statically linked to application

• memory is allocated and deallocated automatically

• use make() or new() to initialize maps, slices and channels

  • new()
  1. allocates memory but does not initialize memory
  2. results in zeroed storage but returns a memory address
  • make()
  1. allocates and initializes memory
  2. allocates non-zeroed storage and returns a memory address
