Username bug

[akbarjorayev]

The code:

export function isValidUsername(username) {
  if (username.length < 2) {
    return { msg: 'Write more than 1 characters', ok: false }
  }

  const hasWhitespace = /\s/.test(username.trim())
  if (hasWhitespace) {
    return { msg: 'Contains whitespace', ok: false }
  }

  const regex = /^[A-Za-z0-9_]+$/
  if (!regex.test(username.trim())) {
    return { msg: 'Invalid characters', ok: false }
  }

  return { msg: 'Valid username', ok: true }
}
