How to organize validation when entering data?

Question

JavaScript

Hello, I need to organize the input of numeric values ​​​​from the console using readline, separated by commas, by pressing a comma, the program checks the entered values ​​for correctness (the presence of letters, special characters), if the data is entered incorrectly, the program displays a message about this, deletes this data and continues typing until the user presses enter. Help someone with what they can, I read a lot of everything, I can’t figure out how to implement it, I will be grateful for useful links on this topic or examples of solving similar problems, thanks!
