I've been researching how to validate e-mail, dates, hours, etc. And in the case of email, I found a code like this: /^.+@.+\..{2,}$/; . He is incomplete. But I wanted to understand what these symbols are, and what do they represent to validate a string?
If someone can clarify how this works I thank you.
The explanation of this regex is like this:
/^.+@.+\..{2,}$/
/ - opening symbol of the regex object. ^ - indicates start of string .+ - any character less line change, one or more occurrences @ - an "at" character \. - the character point, escaped because in regex the point has a function, so with \ means the character itself and not the function that it usually has in regex .{2,} - any character less line change, two followed or longer $ - end of string / - closing the regex object There is a very good site for parsing regex, check it out here: link
