В прежних версиях NodeJS/браузерного JavaScript вы бы использовали «callbacks» (обратные вызовы), что приводит к «callback hell» (ад обратных вызовов).

The built-in function <code>complex</code> constructs a complex
value from a floating-point real and imaginary part, while
<code>real</code> and <code>imag</code>
extract the real and imaginary parts of a complex value.

#### `Hero` - el *modelo de tabla* { #hero-the-table-model }

Luego, crearemos `Hero`, el *modelo de tabla* real, con los **campos extra** que no siempre están en los otros modelos:

are predefined and refer to registers.
The exact set depends on the architecture.

<p>
There are four predeclared symbols that refer to pseudo-registers.
These are not real registers, but rather virtual registers maintained by
the toolchain, such as a frame pointer.
The set of pseudo-registers is the same for all architectures:
