Comparing 2 email addresses in 2 fields with javascript

Question

My requirement is - To compare if 2 email address are different (comparing case as well. if different then to proceed. if same, then to get an error.

tom.smith@gmail.com & Tom.Smith@gmail.com = Same - error should be received.

I am trying to achieve this through javascript. When I match the email addresses as equal even the case (upper/lower) is being considered. But if am trying to check on not equal, the code is not checking the case and no error is appearing.

Code -

if ((context.Email1.value) !== (context.Email2.value)) { 
    return true; 
} else { 
    return false; 
}

Please advice.

Regards, PS

Need more information with respect to code. what is those context? You can however try `context.Email1.toLowerCase().value !== context.Email2.toLowerCase().value` — Guruprasad J Rao, Mar 14 '18 at 04:20
`"tom.smith@gmail.com" == "Tom.Smith@gmail.com"` returns `false`. Or do you want it to return `true`? And don't do `if(cond){return true} else {return false}`, just `return (cond)` — R. Schifini, Mar 14 '18 at 04:24
tom.smith@gmail.com" == "Tom.Smith@gmail.com should return false — user9489154, Mar 14 '18 at 04:27

"tom.smith@gmail.com" != "Tom.Smith@gmail.com" should return false. if this helps — user9489154, Mar 14 '18 at 04:56
then they just have to be equals. you can `.toLowerCase()` these strings in order them to be equals — guijob, Mar 14 '18 at 04:58
