"noexcept" not explained - suggestion

[gfazzito]

Just a suggestion. On page 107 in the pdf (chapter 8: Plug-in parameters), at the top it has the following code:

Change the code in Parameters.h to the following:

#pragma once
#include <JuceHeader.h>

class Parameters
{
public:
   Parameters(juce::AudioProcessorValueTreeState& apvts); 
   static juce::AudioProcessorValueTreeState::ParameterLayout
   createParameterLayout();
// 1
   void update() noexcept;
// 2
   float gain;
// 3
private:
   juce::AudioParameterFloat* gainParam;
}

The explanation of the line n° 1 says:

"1. You added a new function, update(). This where we’ll read the current OutputGain parameter setting and put it into the gain variable."

But it doesn't explain what noexepct is. Maybe adding some text to explain it could be helpful for clearing out any doubts.
For example:

" In C++, the "noexcept" specifier is used to indicate that a function does not throw any exceptions. This specifier can be applied to functions, variables, and pointers or references to functions. Don't worry about this for now as it will be explained more in detail later..."

update: there a note explanation it on the next page (171). Maybe moving that into page 170, as there's a new definition.
