Overview

The new() built-in function takes a type as argument, allocates memory of the given type and returns a pointer to it.

var ptr *some_type
ptr = new(some_type)

We don't have to worry about de-allocating memory allocated with new(). It is automatically garbage collected.

new() and New()

The "errors" package exposes a New() function. Do not mistake it for new().
