Regular Expressions: Match Single Character with Multiple Possibilities - Answers not matching

Tell us what’s happening:
I was testing to see if i can get the same answer using /a|e|i|o|u/gi instead of /[aeiou]/gi . Why is the result false? The arrays in result1 and result2 appear to be identical.

Your code so far


let quoteSample = "Beware of bugs in the above code; I have only proved it correct, not tried it.";
let vowelRegex1 = /[aeiou]/gi; // Change this line
let vowelRegex2 = /a|e|i|o|u/gi;
let result1 = quoteSample.match(vowelRegex1); // Change this line
let result2 = quoteSample.match(vowelRegex2); // Change this line

console.log(result1===result2)

To my knowledge, you cannot compare arrays with the == or === operators. If I convert them to strings, the result changes.

Altough you are right here. This part of the question was to let OP think about what type of code he was writing.
