Good afternoon,
I have a question in an exercise that I have to solve and I wanted to ask you to help me:
As I do a function in Javascript that takes as argument a string and checks if an email is valid, ie if it contains @is an email. And the function returns a boolean. Thank you

You can validate using this function:
function IsEmail(email){
var exclude=/[^@-.w]|^[[email protected]]|[._-]{2}|[@.]{2}|(@)[^@]*1/;
var check=/@[w-]+./;
var checkend=/.[a-zA-Z]{2,3}$/;
if(((email.search(exclude) != -1)||(email.search(check)) == -1)||(email.search(checkend) == -1)){return false;}
else {return true;}
}

Thank you very much!
For those who are trying to consult the source link, the current link is this.
it seems that the regular expression that the exclude variable is receiving is no longer valid

You can use regular expressions to check if the received string is a valid email. Take a look at this link: Regexone He’ll give you a good foundation.
