About Variables

Go is a statically-typed language, which means that everything has a type at compile-time. Assigning a value to a name is referred to as defining a variable. A variable can be defined either by explicitly specifying its type, or by assigning a value to have the Go compiler infer its type based on the assigned value.

var explicitVar int // Explicitly typed
implicitVar := 10   // Implicitly typed

The value of a variable can be assigned using the := operator and updated using the = operator. Once defined, a variable's type can never change.

count := 1 // Assign initial value
count = 2  // Update to new value

// Compiler error when assigning different type
// count = false

Integers

TODO: decide what to do with this section

Integer values are defined as one or more (consecutive) digits and support the default mathematical operators.
