// Declaration
var value int
 
// Initialization
value = 10
 
// Declaration + Initialization + Type inference
var isActive = true
 
// Short declaration (only inside functions)
text := "Hello"
 
// Multi declaration
var i, j, k = 1, 2, 3
 
// Variable not initialized = Zero values
// Numeric: 0
// Boolean: false
// String: ""
// Special value: nil (same as null)
 
var number int // 0
var text string // ""
var boolean bool // false
 
// Type conversions
// T(v) converts v to type T
 
i := 1.234 // float
int(i) // 1
