let userCheck = /^[a-z]{2,}\d*$/i;

Look here

  1. The only numbers in the username have to be at the end. \d$ There can be zero or more of them at the end. * 
/\d*$/;
  1. Username letters can be lowercase and uppercase. i 
/\d*$/i;
  1. Usernames have to be at least two characters long. {2,} A two-letter username can only use alphabet letter characters. ^[a-z] 
/^[a-z]{2,}\d*$/i;

Your regex will match a word that ends with a letter and a number, you need to add quantity specifiers to both. Also you will need also to add the match for the beginning of the string

Quantity specifier because you need at least 2 letters, and then you can 0 or more numbers at the end of the word
