Can you share the disadvantages with code snippets ?

Sorry I don't have the time nor the patience at the moment but I can at least detail my answer :

Simply, if you think about the Signal-to-Noise ratio, nesting ternary operator will more often lead to error when sigh treading and ask more energy to be understood for the sake of a very few line of code.

In this particular case, writing a more explicit comparison will be better for the whole understanding of the code flow. with "ifs" or juste split it in more lines of ternary attribution.

Also, if you should write half a dozen comparison for the attribution of a variable, you should put it in a specific function that will be named accordingly and this will greatly improve this part of the code.

For more information, you can look in the ESLint documentation for this specific code smell :

Also thank you for your post !
