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

Methods in this category support method chaining, enabling multiple modifications to be applied sequentially in a concise and readable manner.

For example, the following chained call:

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

is functionally equivalent to:

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

Method Overview #

• delete(row): Deletes the specified row from the quadrille.
• insert(row): Inserts an empty row into the quadrille at the specified position.
• randomize(): Randomizes the current content of the quadrille, shuffling cell values.
• rand(args): Randomly populates or empties a specified number of cells in the quadrille.
• swap(args): Swaps content between two specified cells or rows as defined by args.
• replace(args): Replaces cell values in the quadrille, either targeting non-empty cells or swapping one value for another.
• clear(args): Clears content from the entire quadrille or specific cells, depending on args.
• fill(args): Fills the entire quadrille or specific cells with a specified value provided in args.

Mutator methods offer you a flexible approach to manipulating quadrille instances, enabling operations such as deletion, insertion, replacement, and randomization of cell content. With support for method chaining, these transformations can be combined seamlessly to perform complex modifications in a clear and concise manner.
