Mutators #

Mutator methods directly modify the state of the quadrille they are called upon. These transformations are persistent and affect the quadrille instance in-place.

Observation
Methods in this category support method chaining, allowing multiple modifications to be applied sequentially in a concise manner. For example, quadrille.clear().fill(5, '🐁').randomize() is functionally equivalent to applying each method separately:

quadrille.clear();
quadrille.fill(5, '🐁');
quadrille.randomize();
