Create a function that accepts a string, checks if it's a valid email address and returns either true or false, depending on the evaluation.

• The string must contain an @ character.
• The string must contain a . character.
• The @ must have at least one character in front of it.
  • e.g. "e@edabit.com" is valid while "@edabit.com" is invalid.
• The . and the @ must be in the appropriate places.
  • e.g. "hello.email@com" is invalid while "john.smith@email.com" is valid.

If the string passes these tests, it's considered a valid email address.

Examples

validateEmail("@gmail.com") ➞ false

validateEmail("hello.gmail@com") ➞ false

validateEmail("gmail") ➞ false

validateEmail("hello@gmail") ➞ false

validateEmail("hello@edabit.com") ➞ true

• You can solve this challenge with RegEx, but it's intended to be solved with logic.
• Solutions using RegEx will be accepted but frowned upon :(
