What's the meaning of " /^[^aeiou]+/ "?

Anybody can tell me what the meaning of “ /^[^aeiou]+/” of the second line is?
Since “^” means negative, then" [^aeiou] +" means consonant or consonant cluster, and “^[^aeiou]+” means positive that are vowels? and what about “y” as it is a vowel sometimes? Anybody can help me with this? Thanks


Pig Latin

Pig Latin is a way of altering English Words. The rules are as follows:

  • If a word begins with a consonant, take the first consonant or consonant cluster, move it to the end of the word, and add ay to it.

  • If a word begins with a vowel, just add way at the end.

Translate the provided string to Pig Latin. Input strings are guaranteed to be English words in all lowercase.
Your code so far

function translatePigLatin(str) {
let consonantRegex = /^[^aeiou]+/;
let myConsonants = str.match(consonantRegex);
return myConsonants !== null
  ? str
      .replace(consonantRegex, "")
  : str.concat("way");

the ^ negates a character class, yes. but outside of the square bracket it is an anchor for the start of the string

Wow, thanks, I get it

I didn’t get this code neither. Why there are two ^s? Isn’t one ^ enough to represent the anchor of the start of the string?

The second applies to the character class (the stuff between the square brackets). It doesn’t have anything to do with anchoring. As @ilenia said: “the ^ negates a character class.”

yeah bro you are right

See here /[1]+/ 1st ^ refers to the first element of the string and 2nd ^ refers to the negetion
