How to handle 'FrozenError' when modifying elements in a frozen array in Ruby 3.2?
I'm working on a project and hit a roadblock... This might be a silly question, but I'm working with a `FrozenError` when trying to modify elements in an array that I've frozen in Ruby 3.2. I have a scenario where I need to freeze an array to ensure its immutability, but later in the code, certain operations require modifying that array. Here’s a simplified version of my code: ```ruby frozen_array = [1, 2, 3].freeze # Later in the code, I attempt to modify it: frozen_array[0] = 10 # This line raises an behavior ``` When I run the above snippet, I receive the following behavior: ``` FrozenError: need to modify frozen Array ``` I read that freezing an object prevents any changes to it, which is what I intended. However, I need the flexibility to update this array based on some conditions later in my method. One workaround I considered is to duplicate the frozen array before modifying it: ```ruby mutable_array = frozen_array.dup mutable_array[0] = 10 ``` While this works, I’m concerned about performance overhead, especially if this method is called frequently or if the array is large. Is there a better design pattern or best practice for handling this situation without compromising performance? Should I consider using a different data structure or approach to maintain immutability while allowing for updates? Any suggestions would be greatly appreciated! For context: I'm using Ruby on macOS. How would you solve this? My development environment is Windows. Am I missing something obvious?
