I thought the “^” regex operator will match if whatever follow it is the start of the string ? Not to check if the string doesn’t contain the following pattern
Solved . Thank you
the caret ^ have two functions:
1 - at the beginning of the regex it will make the match start at the beginning of the string - ex: /^[0-9]/ the string must start with a number
2 - inside a characters will negate the character class /[^0-9]/ it will match not number characters
putting the two together: /^[^0-9]/ the string can’t start with a number
