Match the same start and end character of a string with Regex

Question

I\'m trying to match the start and end character of a string to be the same vowel. My regex is working in most scenarios, but failing in others:

var re = /([aeio

Just a different version of @Hristiyan Dodov answer that I have written for fun.

regex = /^(a|e|i|o|u).*\1$/

const strings = ['abcde', 'abcda', 'aabcdaa', 'aeqwae', 'ouqweru']

strings.forEach((e)=>{
  const result = regex.test(e)
  console.log(e, result)
})
